Introduction

This document provides a number of example applications for the use of Siemens Gigaset devices for local networks. It describes the most frequently used of the variety of options that these Siemens products offer you. This chapter provides an overview of the various network configurations and possible applications. The following chapters provide more detailed descriptions of how to use these options. Please note: u The user interfaces depicted in this guide may differ from those on your screen because of the settings you have made. For Windows screens, the default state has been presented. There may also be minor differences due to different update cycles of user interface and this manual.

u wireless linked PCs to the Internet and u connect PCs with a wireless connection to a wired network.
Infrastructure mode is the standard configuration for the Gigaset SE551 WLAN dsl/ cable. This configuration is described in the quick guide enclosed with the router. Connecting wireless networks to the Internet The Gigaset SE551 WLAN dsl/cable has a WAN interface that permits simultaneous access of all the stations to the Internet. To use this feature, you will need a DSL or cable connection from an Internet Service Provider. Please check whether your Internet Service Provider supports parallel access by several PCs.

Linking a wireless network (WLAN) to a wired network (LAN) A major advantage of wireless networks is their ability to work easily with existing wired networks. You can set up a wireless network to link mobile stations with an existing wired network. This requires all the stations in the wireless network to work in infrastructure mode.
Wireless local network (WLAN)

((( ))) Access point

The Gigaset SE551 WLAN dsl/cable has four Ethernet interfaces (LAN ports). Up to four PCs can be connected directly to these LAN ports. These PCs also access the Internet via the Gigaset SE551 WLAN dsl/cable. Please note: You can also connect an Ethernet router to a LAN port, providing access to a larger wired network. If you want to connect the Gigaset network to an existing network, a variety of settings need to be taken into account. Therefore we cannot provide a general example for this use; the configuration depends greatly on the networks in question. We advise having configuration of such a network carried out by an expert.
Introduction Extending a wireless network using a repeater
You can use a repeater, e.g. the Gigaset WLAN Repeater 108 to extend the coverage of your wireless network. To do this, set it up at the limit of the range of your wireless network. The Gigaset WLAN Repeater will now transmit data traffic into its own wireless area. This technology allows you to set up wireless networks that cover a much larger area than would be possible with the Gigaset SE551 WLAN dsl/cable alone.
Gigaset WLAN Repeater ((( )))
PCs to be connected in a wireless local network via a Gigaset WLAN Repeater must be equipped with a wireless network adapter.

u After that, users who want to use other users' files or printers can make them avail-
able on their PC. This is described in Chapter "Using released files and printers" from page 49.
Network configuration, release and use differ depending on the Windows operating system used. Please note: If you are using Windows 2000 on your network, you have to set up for all users who are to have access to resources on a Windows 2000 PC the appropriate user IDs on the Windows 2000 PC and their own PCs. The following table provides an overview as to where you can find the relevant information. Windows XP Setting up the network Releasing your files Releasing your printers Setting up user names Using files on other PCs Using printers on other PCs page 15 page 21 page 23 page 50 page 53 page 55 Windows 2000 page 24 page 32 page 36 page 29 page 58 page 61 Windows 98 page 37 page 46 page 47 page 63 page 66 page 69

If this printer is to be accessed by users with PCs that have a different operating system, you will have to install additional drivers. To do this click Additional drivers. and follow the instructions.
Use Apply to save the current settings. Click OK to close share configuration.
Making your own files and printers available (WIN 98 / 98 SE / ME)
To release files or printers on a PC with Windows 98 for other users on the network: 1. Set up PC as Client for Microsoft Networks (see page 37). 2. Select computer names and workgroup (see page 40). 3. Select type of access control (see page 40). 4. Set TCP/IP protocol (see page 41). 5. Install utilities for file and printer release (see page 44). 6. Release files and printer (see page 46).
Setting up a PC as Client for Microsoft Networks
Before the PCs in your network can access shared resources, you have to define a Microsoft Network, i.e. all the PCs have to be configured as Clients of a Microsoft Network. This can be done as follows:
Open the Control Panel and then open Network. Check whether the list of components contains the entry Client for Microsoft

Networks.

If the entry exists, please continue from page 40.

If the entry does not exist, click Add.
Select as network component type Client and click Add. Select in Manufacturers the entry Microsoft and in Network clients the entry
Client for Microsoft Networks before confirming with OK.
In the Network window move from Configuration to the Identification tab. In the Computer name box, enter the name the PC is to appear under on the network. This name must be unique within the network.
The Description box can be left empty.
Selecting the access control
Now you can define which access rights are to be assigned to resources you want to release.
In the Network window move from Identification to the Access control tab.
Use the option Access control at release level to define that access to released files or printer is to be password protected. The option Access control at user level defines that access is permitted only for certain users or groups.
The TCP/IP protocol ensures that the PCs on the network can communicate with each other. This protocol requires certain settings which you will now make so that it can function smoothly. Checking the TCP/IP entry
In the Network window, check that there is a TCP/IP > entry for your network card
or network adapter in the list of components. To do this, in the Network window, switch to the Configuration tab. If for example you are using a Gigaset PC Card 108 as the wireless network adapter, the list must contain the entry TCP/IP > Siemens Gigaset PC Card 108.
If the entry for your network card or network adapter is there, please turn to

page 41.

Select as network component type Protocol and click Add. Select in Manufacturers the entry Microsoft and in Network protocol the entry
TCP/IP before confirming with OK.

Set TCP/IP protocol.

To do this, in the Network window, switch to the Configuration tab. Select the TCP/IP > entry for your network card and click Properties.

Using files and printers on the network (Windows XP)
You can use resources on your PC such as files and printers that have been made available by other PCs. If the resource you want to use on your PC is on a Windows 2000 system then you have to set up user accounts for all the users who are to have access. The same user IDs have to be entered as on the releasing system.
Setting up a user account
To set up a user account:
Open the Control Panel and then User accounts.
Select Create new account. Enter a name for the user. Click Next.
Select Limited as account type. Then the newly created user will not have any
administrator rights on your PC.
Click Create account. You will now see the new user account.
You should now assign a password. To do this click the new user account. Select Create Password.
Enter a password and then enter it again as confirmation. Click Create Password.
Using released files and printers Accessing released drives or folders from your PC
You can access drives and folders released on other PCs in two different ways:
u via the My NetworkPlaces of your PC (see page 66).
You should choose this alternative if for example you want to copy files or folders from another PC to your own or vice versa.
u by hooking on to your PC's file system (see page 53).
You should choose this alternative if you want to work directly with the files or folders of the other PC. In this case, hook on an entire released drive or folder in your PC's file system and work with the files as if they were files on your PC. Please note: Drives or folders can be simultaneously hooked onto several PCs. It is therefore possible for other users to access the data. Most applications (e. g. word processing software) lock files once they have been opened. This prevents inconsistent data pools. If you cannot open a file because it is locked, you will normally see a message to that effect. To hook up network drives:
Open the Desktop. In the Extras menu, select Map network drive.
Select the drive name under which the remote drive is to be hooked on to your PC.
Enter a name under which the drive or folder is to be released for the network. To do
this click Browse. This will open a screen in which you can search the network environment.
Select the resource you want and click OK.
If you select the option Reconnect at logon, Windows will hook the drive on every
time you start your PC, provided the remote PC is running.

Click Finish. Now open the desktop. The remote drive is now available as the network drive. You
can access the files as if they were on your own PC.
Using released files and printers Accessing released printers from your PC
If there is a printer on your local network and it has been released, you can use it to print out your data. To do this you have to set it up on your PC as the network printer. This can be done as follows:
Open the printer manager with Printers and Faxes in the Start menu.
Select Add printer. This opens the printer installation wizard. Click Next. In the next window select Network printer or printer connected to another computer.
Click Next again. Select Browse for a printer to look for the printer on the network.
Click Next. This will open a screen in which you can search the network environment

for the printer.

Select the printer you want and click Next.
Complete printer installation with Finish.
The newly installed printer will now appear in the printer list and can be used just like a local printer.
Using files and printers on the network (Windows 2000)
You can use resources on your PC such as files and printers that have been made available by other PCs. To do this you have to make these resources available on your PC.

Setting up user names

To access files or printers on a Windows 2000 computer, you must set up a user name that corresponds to the release. This user name must also have been set up on the system which is releasing the files or printers. That is why setting up a user name has already been described in Chapter "Releasing files and printers for shared use" in the section "Setting up user names" on page 29.
Accessing released drives or folders from your PC
u by hooking on to your PC's file system (see page 59).
You should choose this alternative if you want to work directly with the files or folders of the other PC. In this case, hook on an entire released drive or folder in your PC's file system and work with the files as if they were files on your PC. Please note: Drives or folders can be simultaneously hooked onto several PCs. It is therefore possible for other users to access the data. Most applications (e. g. word processing software) lock files once they have been opened. This prevents inconsistent data pools. If you cannot open a file because it is locked, you will normally see a message to that effect.

To hook up network drives:
Open the My NetworkPlaces and then Computers near me.
Open the PC containing the resources you want to access with a double click. You
will now see the shared resources on that PC.
Left-click the resource you want to attach to your PC and open the pop-up menu
with the right-hand mouse button Map network drive.
Select the drive name under which the remote drive is to be hooked on to your PC. Enter a name under which the drive or folder was released or click Browse. This will
open a screen in which you can search the network environment.
Click Finish. Now open the Desktop. The remote drive is now available as the network drive. You
Accessing released printers from your PC
Open the printer manager with Start Settings Printers. Click the Add printer icon. This opens the printer installation wizard. Click Next. In the next window select Network printer. Click Next again. Select Enter printer name or click "next" to look for a printer and click Next. This will open a screen in which you can search the network environment for the printer.
Answer the prompt whether the printer is to be used as the standard printer with Yes

or No and click Next.

Using files and printers on the network (Win 98 / 98 SE / ME)
You can use resources on your PC such as files and printers that have been released by other PCs. Please note: If the resource you want to use on your PC is on a Windows 2000 system then you have to set up user IDs for all the users who are to have access. The same user IDs have to be entered as on the releasing system.

To set up a user ID:

Open the Control Panel and then open User. If there are no user entries yet, you will see a welcome screen. Confirm this with

Next. Next.

If there are user names already, you will see the user list. Click New user and then
Enter a user name and click Next. Enter a password, repeat it and click Next. Define the settings for the user's interface. If you want to apply the current settings
for the user, click Next.
The user has now been registered.
Either enter further users or close user administration with Close.
u by hooking on to your PC's file system (see page 67).
You should choose this alternative if you want to work directly with the files or folders of the other PC. In this case, hook on an entire released drive or folder in your PC's file system and work with the files as if they were files on your PC. Please note: Drives or folders can be simultaneously hooked onto several PCs. It is therefore possible for other users to access the data. Most applications (e. g. word processing software) lock files once they have been opened. This prevents inconsistent data pools. If you cannot open a file because it is locked, you will normally see a message to that effect. Accessing external files via the My NetworkPlaces If the network has been set up on all the PCs with the same workgroup, then you can access released drives and folders via your PC's network environment. You will find the My NetworkPlaces both as an icon on your PC desktop and also in the file tree in the left-hand pane of Windows Explorer. The illustration depicts as an example the My NetworkPlaces in Windows Explorer. In the My NetworkPlaces you will find the entry Entire network, under this the workgroup to which the PCs have been assigned and then the names of all the PCs comprising this workgroup. Workgroups are marked with the symbol:

u electronic mail (email) u World-Wide Web (WWW) u file transfer (FTP) u discussion forums (Usenet / Newsgroups)
Internet Service Provider An Internet Service Provider offers access to the Internet for a fee. IP Internet Protocol The IP Protocol is one of the TCP/IP protocols. It is responsible for the addressing of participants in a network using IP addresses and routes data from the sender to the recipient. It decides the paths along which the data packets travel from the sender to the recipient in a complex network (routing). IP address An IP address is a network-wide unique address of a network component in a network based on the TCP/IP protocol (e. g. in a local network (LAN) or on the Internet). The IP address has four parts (decimal numbers) separated by periods (e. g. 192.168.2.1). The IP address comprises the network number and the computer number. Depending on the Subnet mask one, two or three parts form the network number, the remainder the computer number. You can find out the IP address of your PC using the ipconfig command. IP addresses can be assigned manually (see Static IP address) or automatically (see Dynamic IP address). On the Internet Domain names are normally used instead of the IP addresses. DNS is used to assign Domain names to IP addresses. The Gigaset SE551 WLAN dsl/cable has a Private IP address and a Public IP address. IP address pool The Gigaset SE551 WLAN dsl/cable IP address pool defines a range of IP addresses that the router's DHCP Server can use to assign Dynamic IP addresses. IPSec Internet Protocol Security The term IPSec covers a number of Protocols used for encrypted transmission of data packets over the Internet. IPSec uses digital certificates for device authentication. IPSec is offered by Internet Service Providers for implementing Virtual Private Networks (VPN). See also: PPTP, L2TP ISP Internet Service Provider see Internet Service Provider L2TP Layer Two Tunneling Protocol L2TP is an extension of PPTP and is offered by Internet Service Providers for implementing Virtual Private Networks (VPN). It covers most of the features of PPTP but with less overhead and is better for managed networks.
LAN A local network links network components so that they can exchange data and share resources. The physical range is restricted to a particular area (a site). As a rule the users and operators are identical. A local network can be connected to other local networks or a wide-area network (WAN) such as the Internet. You can use the Gigaset SE105 dsl/cable to set up both a wired local Ethernet network and also as wireless network as per the IEEE 802.11g standard. Local IP address See Private IP address MAC address Media Access Control The MAC address is used for the globally unique identification of a Network adapter. It comprises six parts (hexadecimal numbers), e. g. 00-90-96-34-00-1A. The MAC address is assigned by the network adapter manufacturer and cannot be changed. Mbps Million bits per second Specification of the transmission speed in a network. MRU Maximum Receive Unit The MRU defines the maximum payload data within a data packet. MTU Maximum Transmission Unit The MTU defines the maximum length of a data packet that can transported over the network at a time. NAT Network Address Translation NAT is a method for implementing IP addresses (mostly Private IP addresses) in a network on one or more Public IP addresses on the Internet. With NAT several network components in a LAN can share the router's public IP address to connect to the Internet. The network components of the local network are hidden behind the router's IP address registered on the Internet. As a result of this security function NAT is frequently used as part of the network Firewall. If you want to make services on a PC on the local network available on the Internet despite NAT, you can configure the Gigaset SE551 WLAN dsl/cable as a Virtual server. Network A network is a group of devices connected in wired or wireless mode so that they can share resources such as files and peripherals. A general distinction is made between local networks (LAN) and wide-area networks (WAN).

Network adapter The network adapter is the hardware device that realises the connection of a network component to a local network. The connection can be wired or wireless. A wired network adapter is for example an Ethernet network card. Wireless network adapters are for example the Gigaset PC Card 108 and Gigaset USB Adapter 108. A network adapter has a unique address, the MAC address. Port Data is exchanged between two applications in a network via a Port. The port number addresses an application within a network component. The combination of IP address/ port number uniquely identifies the recipient or sender of a data packet within a network. Some applications (e. g. Internet services such as HTTP or FTP) work with fixed port numbers, others are allocated a free port number every time they need one. Port Forwarding In Port Forwarding the Gigaset SE551 WLAN dsl/cable directs data packets from the Internet that are addressed to a particular Port to the corresponding port of the appropriate network component. This enables servers on the local network to offer services on the Internet without them needing a Public IP address. See also: Virtual server PPPoE Point-to-Point Protocol over Ethernet PPPoE is a Protocol for connecting network components in a local wired network to the Internet via a modem. PPTP An Internet connection using PPTP Protocol that creates a "tunnel" within an Internet connection for secure private connection in which the data is sent in encrypted form. The PPTP protocol is used in a Virtual Private Network (VPN). Private IP address The private IP address is is a network component's address on the local network (LAN). The network operator can assign any address he or she wants. Devices that act as a link from a local network, such as the Gigaset SE551 WLAN dsl/cable, have a private and a Public IP address. Protocol A protocol describes the agreements for communicating on a network. A protocol contains rules for opening, administering and closing a connection, about data formats, time frames and error handling. Communications between two applications require different protocols at various levels, e. g. the TCP/IP protocols for the Internet. Public IP address The public IP address is a network component's address on the Internet. It is assigned by the Internet Service Provider. Devices that act as a link from a local network, such as the Gigaset SE551 WLAN dsl/cable, have a public and a Private IP address.
Re-key Interval The re-key interval is the period after which new keys are automatically generated for data encryption with WPA-PSK. Remote Management Remote Management describes the possibility of administering a network from a network component that is not on the local network (LAN) itself. Roaming Roaming involves the use of several routers to extend the range of a network. The PCs on the network can switch dynamically between several Access Points. Router A router directs data packages from one local network (LAN) to another via the fastest route. A Router permits the connecting of network with different network technologies. For example, it can link a local network with Ethernet or WLAN technology to the Internet. See also: Bridge, Switch, Hub, Gateway Server A Server makes a service available to other network components (Clients). Frequently the term Server is used for a computer. But it can also mean an application that provides a particular service such as DNS or Web service. SMTP Simple Mail Transfer Protocol The SMTP Protocol is part of the TCP/IP protocol family. It governs the exchange of electronic mail on the Internet. Your Internet Service Provider provides you with access to an SMTP server. SSID Service Set Identifier The SSID identifies the stations of a wireless network (WLAN). All the wireless network components with the same SSID form a shared network. The SSID can be freely assigned. Static IP address A static IP address is assigned to a network component manually during network configuration. Unlike a Dynamic IP address, a static IP address never changes. Subnet mask The subnet mask determines how many parts of the IP addresses of a network represent the network number and how many the computer number. The subnet mask administered by the Gigaset SE551 WLAN dsl/cable is always 255.255.255.0. That means the first three parts of the IP address form the network number and the final part is used for assigning computer numbers. The first three parts of the IP address of all network components are in this case always the same.

Super G Super G technology can increase the transmission rate in the network to up to 108 Mbps by using channel bundling. Subnetwork A subnetwork divides a network into smaller units. Switch A Switch, like a Hub, is an element for linking different network segments or components. Unlike a hub, the switch has its own intelligence that enables it to further packets to only that subnetwork or network component they are meant for. See also: Bridge, Hub, Router, Gateway TCP Transmission Control Protocol The TCP Protocol is part of the TCP/IP protocol family. TCP handles data transport between communication partners (applications). TCP is a session-based transmission protocol, i.e. it sets up, monitors and terminates a connection for transporting data. See also: UDP TCP/IP Protocol family on which the Internet is based. IP form the basis for every PC-to-PC connection. TCP provides applications with a reliable transmission link in the form of a continuous data stream. TCP/IP is the basis on which services such as WWW, Mail and News are built. There are other protocols as well. Tunneling Tunneling is a procedure in which the data traffic of the one Protocol is transmitted with the help of a different protocol. For example, data packets of a private network can be packed in IP packets and transported over the Internet as if in a tunnel. Tunneling procedures are used nowadays for the secure transmission of data in a Virtual Private Network (VPN). The IP packages from a local network are encrypted and transmitted over the Internet using a tunnelling protocol (e. g. PPTP). UDP User Datagram Protocol UDP is a Protocol of the TCP/IP protocol family that handles data transport between communication partners (applications). Unlike TCP UDP is a non-session based protocol. It does not establish a fixed connection. The data packets, so-called datagrams, are sent as a Broadcast. The recipient is responsible for making sure the data is received. The sender is not notified about whether it is received or not. UPnP Universal Plug and Play UPnP technology is used for the spontaneous linking of home or small office networks. Devices that support UPnP carry out their network configuration automatically once they are connected to a network. They also provide their own services or use services of other devices on the network automatically.
URL Universal Resource Locator Globally unique address of a Domain on the Internet. Virtual server A virtual Server provides a service on the Internet that runs not on itself but another network component. The Gigaset SE551 WLAN dsl/cable can be configured as a virtual server. It then directs incoming calls for a service via Port Forwarding directly to the appropriate Port of the network component in question. VPN A VPN is a network connection in which the data are transmitted over the Internet using special Tunneling protocols (e. g. PPTP, L2TP, IPSec) securely, i.e. encrypted. VPNs are used to connect private networks at different locations with each other without having to lease a transmission line. The Internet is used instead. WAN Wide Area Network A WAN is a network that is not restricted to one particular area, such as the Internet. A WAN is run by one or more public providers to enable private access. You access the Internet via an Internet Service Provider. WEP Wired Equivalent Privacy WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wireless transmissions in a WLAN against unauthorised access through Encryption of the data transmitted. Wireless network See WLAN WLAN Wireless LAN Wireless LANs enable network components to communicate with and access a network using radio waves as the transport medium. A wireless LAN can be connected as an extension to a wired LAN or it can form the basis for a new network. The basic element of a wireless network is the so-called wireless cell. This is the area where the wireless communication takes place. A WLAN can be operated in Ad-hoc mode or Infrastructure mode. WLAN is currently specified in Standard IEEE 802.11. The Gigaset SE551 WLAN dsl/cable complies with Standard 802.11g. WPA WPA was developed to improve security provided by WEP. To generate keys, WPA uses more complex methods, e.g. TKIP (Temporal Key Integrity Protocol). In addition, WPA can use an authentication server (e.g. a RADIUS server) to increase security.

WPA-PSK WPA Preshared Key: Variant of WPA data encryption, in which new keys are automatically generated at regular intervals by means of a keyword (Pre-shared key). The key is updated after defined periods (Re-key Interval). XR eXtended Range The Access Point's XR function (Extended Range) is activated if the range is too large to establish a connection. It increases the range and, at the same time, decreases the transmission rate.

Linking a wireless network (WLAN) to an Ethernet (LAN) A major advantage of wireless networks is their ability to work with existing Ethernet networks. You can set up a wireless network to link mobile stations with an existing wired network. This requires all the stations in the wireless network to work in infrastructure mode.
Wireless local network (WLAN)

((( ))) Access point

The Gigaset SE505 dsl/cable has four Ethernet LAN ports. Up to four PCs can be connected directly to these LAN ports. These PCs also access the Internet via the Gigaset SE505 dsl/cable. You can also connect an Ethernet router to a LAN port for access to a larger Ethernet. If you want to link the Gigaset WLAN network to an existing network, a large number of settings have to be applied. Therefore we cannot provide a general example for this use; the configuration depends greatly on the networks in question. We advise having configuration of such a network carried out by an expert.

((( ((( ((( (((

Introduction Roaming
Roaming allows connected users (PCs) to move freely between the various access points in a wireless local network without breaking the contact to the network. As soon as the wireless contact might be lost, the PC automatically looks for a different access point with a stronger signal. This technology permits the setting up of wireless networks that cover a much larger area than one access point alone could do. In addition, more users can be accommodated with the many access points. The main areas of use for WLANs with roaming are company sites and universities.

Access Points

In a roaming network, all the users must use the same SSID (see page 31) and encryption (see page 33). The access points have to be connected via a shared wired network (Ethernet). This means you have to operate the Gigaset SE505 dsl/cable in bridge mode. Please consult the operating instructions supplied on the CD.

Possible uses

No matter which type of network you have opted for, Gigaset products for local networks offer a wealth of uses. N Shared use of files You can turn a PC on the network into a file server. All the central data is then stored on this PC. Users on other PCs can hook up folders or entire drives on this file server to their own PCs and work with them as if they were actually on their local PC. Various access rights can be assigned. How to release files for access to users on other PCs is described in Chapter "Sharing files and printers", for Windows 98, 98 SE, ME from page 68 for Windows XP from page 86 for Windows 2000 from page 106 How to make released files on other PCs available on your PC is described: for Windows 98, 98 SE, ME from page 74 for Windows XP from page 92 for Windows 2000 from page 111 N Shared use of printers A printer is connected to a PC. In a network all the users can print their files using this one printer. How to release printers for users on other PCs is described in Chapter "Sharing files and printers": for Windows 98, 98 SE, ME from page 70 for Windows XP from page 88 for Windows 2000 from page 110 How to make the printer connected to another PC available on your PC is described: for Windows 98, 98 SE, ME from page 77 for Windows XP from page 95 for Windows 2000 from page 115

N Remember that the SSID and the WEP key have to be the same on all

the wireless components.

N Before you change your Gigaset SE505 dsl/cable settings, we
recommend that you back up the current functioning state of the router first! To do this select in Advanced Setup Administration -Backup and Restore. Click Backup, follow the dialogue that appears and save your settings.
The Gigaset SE505 dsl/cable has a security setup that guides you step by step through the most important configuration actions for router security. This can also be done via Advanced Setup. Here we will describe configuration using Security Setup with appropriate references to the corresponding functions in Advanced Setup.

Launching Security Setup

To launch Security Setup: N Launch your Web Browser. N Enter the router IP address in the Web Browser address bar. If you have not configured the router with a different IP address, this will be http://192.168.2.1 You will then see a login window: N If a password has already been assigned, enter it and click LOGIN. N After logging in, select Security Setup. Security Setup takes you through the following steps: 1. Assign configuration password (see page 30) 2. Change the router's SSID (see page 31) 3. Set WEP encryption (see page 33) 4. Set up access control (see page 36) 5. Back up the configuration (see page 39)
Protecting your configuration with a password
After installation, your router configuration is not yet protected with a password. To prevent unauthorised changes to the configuration, you should assign a password and change this password from time to time.
N Enter a password in the Enter new password box and repeat it in the box
underneath. The password must be between 3 and 32 characters long. It is not case sensitive. Avoid names and all too obvious words. Mix letters and numbers. Remember the password that you have assigned. If you ever forget the password you will have to reset your router. This can be done by switching the router off, pressing the reset button on the back and switching the router on again while keeping the reset button pressed. Please bear in mind that this will restore all the settings to the factory configuration. No password will be active either.
N To apply the settings click NEXT.
Use the following function in Advanced Setup if you want to change the password later on: Administration Management
Changing the SSID and disabling Broadcast
A wireless network is defined by giving all the components an identical SSID (Service Set ID). The factory setting for the router's SSID is ConnectionPoint. You should change this setting to make sure that nobody can log in to the network unnoticed. You should also prevent the SSID being included in the data packets sent over the network. This could allow persons eavesdropping on the data traffic to gain unauthorised access to your network. Carry out the following steps: 1. Change the SSID on your router and define that it should no longer be visible. 2. Change the SSID accordingly for all wireless network adapters on all PCs(see page 40). You will be changing your router's SSID in the next step of Security Setup.

Configuring security features Setting WEP encryption on the router
In the next step of the Security Setup you will set the WEP encryption on your router.
N Select the encryption mode: 64 or 128-bit.
The Web page then has an added section where you can enter the key. The following illustration shows the page after selecting a 128-bit key.
If you choose hexadecimal, you can use characters 0 to 9 and A to F. With an encryption depth of 64 bits, the key is exactly 10 characters long. An example of a valid key would be: 1234567ABC. With an encryption depth of 128 bits, the key is exactly 26 characters long. An example of a valid key would be: 234567ABC8912345DEF1234567.
If you choose ASCII, you can use characters 0 to 9 and A to F and the special characters of the ASCII character set. With an encryption depth of 64 bits, the key is exactly 5 characters long. An example of a valid key would be: GIGA1. With an encryption depth of 128 bits, the key is exactly 13 characters long. An example of a valid key would be: GIGASET_SE505.
N It is very important to make a note of the key you enter. You will
need this information to configure the wireless network adapters properly. N Do not use the values in this example for your configuration.
Use the following function in Advanced Setup if you want to change the WEP key later on: Wireless settings WEP mode
Once you have completed Security Setup, you have to change the WEP encryption on the wireless network adapters of the connected PCs as well, otherwise they will no longer have access to the router's wireless network. How to do this for a Siemens Gigaset PC Card 54 or Siemens Gigaset PCI Card 54 is described on (see page 41).
Setting up access control
In the next step of Security Setup you can decide which PCs are to have wireless access to your router and thus to your local network. Access is controlled via the MAC addresses of the PCs' network adapters. These MAC addresses are entered in a MAC access table. Once the access control is activated, only those PCs that are in the table can connect to the Internet. The table can hold up to 16 entries. If you intend to activate MAC access control, you should enter at least the PC you want to use for configuring the router. Otherwise you will no longer have any access to the router's user interface. You will receive a warning message to that effect. If you accidentally exclude all PCs from accessing the router, there are two options available: N You can completely reset the router. This can be done by switching the router off, pressing the reset button on the back and switching the router on again while keeping the reset button pressed. Please bear in mind that this will restore all configurations to the factory settings. N You can connect a PC to the router via one of the LAN sockets. As MAC access control only applies for PCs connected in wireless mode, you can then use the PC for changing the router's configuration.

The default setting for access control is deactivated. That means all the PCs using the correct SSID can register. To retain this setting click NEXT.
To activate access control : N Select MAC access table. The last defined access table will be shown and activated. Only these PCs can now register with the router. If you are using this function for the first time, you will have to define a MAC access table.
You can do this in two different ways: N Using the list of registered PCs Use this option if the IP addresses on the local network are assigned by the router's DHCP server and the corresponding PCs are registered. In this case, check the List of active booked in devices option. Then select from the list all the PCs that are to have access and then click Add to list. If you want to add PCs to the table that are not registered at the moment, first deactivate the MAC access table, register all the PCs you want to include in the table with your router and then reactivate the MAC access table.
N By direct entry of the MAC address
Use this option if the IP addresses are not assigned by your router's DHCP server but are static or if the PCs you want to include are not registered with the router at the moment.
You can find the MAC addresses of the PCs' wireless network adapters using MS-DOS prompt with the command ipconfig /all on the PCs in question.
In this case, check the MAC address option.
Enter all the MAC addresses of the PCs that are to have access. The table is easier to handle if you assign a name to the PC and then click Add to list.
N To delete an entry from the table, click delete in the right-hand column of the table

entry.

Use the following function in Advanced Setup if you want to add or change the access control later on: Wireless settings Access control
Backing up the configuration
In the final stage of Security Setup you can back up your router settings to a file and store it on your PC or other data medium. All the current settings are backed up, including those you made before e. g. in Basic Setup or Advanced Setup. If needed, you can use this file to restore the current configuration of your router. Backed-up data can be restored using the Administration Backup and Restore menu item in Advanced Setup.
N If you want to back up the current settings, enable Save configuration to PC. If you
do not want to back up the current configuration, disable this option.
N Click FINISH to close Security Setup.
If you have enabled Save configuration to PC, the file download window will appear in your Browser. Enter where you want to save the file. The Security Setup settings are now active on your router.
Use the following function in Advanced Setup if you want to back up the configuration settings later on: Administration Backup and Restore

Internet games

Your Gigaset Router comes provided with the NAT (Network Address Translation) function. With Address Mapping several users on your local network can access the Internet via one or more public IP addresses. In the default setting, all the local IP address are mapped to your router's public IP address. One property of NAT is that data from the Internet is not allowed into your local network unless it has been explicitly requested by one of the PCs on that network. Most Internet applications run behind the NAT firewall without any problems. If you request Internet pages, for example, or send and receive emails, the request for data from the Internet comes from a PC on the local network and so the router allows the data through. The router opens exactly one port for the application. A port is an internal PC address through which the data is exchanged between a server on the Internet and a client on a PC in the local network. Communicating via a port follows the rules of the TCP or UDP protocol. If an external application tries to send a call to a PC within the local network, the router will block it. There is no open port via which the data could enter the local network. Some applications, such as games on the Internet, require several links, i.e. several ports, so that the players can communicate with each other. In addition, these applications must also be permitted to send requests from other players on the Internet to the player on the local network. These applications cannot work if NAT is active. If you want to use such applications nevertheless, then you will have to set up Port Forwarding for them. With Port Forwarding (directing requests to certain ports) you order the router to send requests from the Internet for a particular service, in this case a game, to the appropriate port(s) on the PC running the game.

Starting configuration

To start configuration: N Launch your Web Browser. N Enter the router IP address in the Web Browser address bar. If you have not configured the router with a different IP address, this will be http://192.168.2.1 You will then see a login window: N If a password has already been assigned, enter it and click LOGIN. N After logging in, select Advanced Setup. N Open the Virtual server menu. N Select Virtual server Port Forwarding.
Setting up Port Forwarding for games
The following example describes the Port Forwarding configuration for N the game "MSN-GAMING-ZONE" on PC "My_PC". The configuration of this game has been predefined and only needs to be applied. The PC must be registered with the router. N the game "My_Game" on PC "My_GamesPC". The configuration for this game has not been predefined and so you will have to configure it yourself. The PC is currently not registered with the router. Setting up Port Forwarding for MSN-GAMING-ZONE

Setting up Port Forwarding for your own services N Select Define service manually
N Enter the name of the service, select the protocol and specify the external port on
which messages for this service are expected and the internal port they are to be redirected to.
You can specify a block of ports using a dash (e. g. 8181-8185) and several port numbers separated by commas (e. g. 8181,8185).
N Now select the PC running the service. To do this click Select PC>>.
N Select Select PC manually.
N Enter the PC's name and MAC address.
N Click Add to list. N Click APPLY. A new entry for the service and the PC will be displayed in the list.
Setting up demilitarised zones for servers
By default access from the Internet to PCs on the local network is not permitted. The router shields the local network with a firewall. Some applications cannot work properly behind a firewall. In this case you can open one PC for unrestricted Internet access in both directions. You define a so-called demilitarised zone (DMZ) for this PC. If you define a DMZ, all the requests from the Internet for a service will be redirected to that PC if the service in question has not already been redirected to another PC via Port Forwarding (see page 52).
A PC in such a demilitarised zone is freely accessible for the Internet and thus may constitute a security risk for your local network.
To set up a DMZ: N Select in the left-hand pane the entry Virtual server DMZ
N Select DMZ. If no DMZ has been defined (no entry in the table), you will now have
to select a PC for the DMZ.
N Select the PC you want to use. There are two ways of doing this: You can
Select the PC from the list Select PC manually
N Select one of the registered PCs from the list or enter the PC's name and MAC

address.

You can find the MAC addresses of the PCs' wireless network adapters using MS-DOS prompt with the command ipconfig/all on the PCs in question.

Setting up a PC as Client for Microsoft Networks
Before the PCs in your network can access shared resources, you have to define a Microsoft Network, i.e. all the PCs have to be configured as Clients of a Microsoft Network. This can be done as follows: N Open the Control Panel and then open Network.
N Check whether the list of components contains the entry Client for Microsoft

Networks.

If the entry exists, please continue from page 62.
N If the entry does not exist, click Add
N Select as network component type Client and click Add. N Select in Manufacturers the entry Microsoft and in Network clients the entry
Client for Microsoft Networks before confirming with OK.
Sharing files and printers Selecting computer names and workgroup
Now you have to specify a name for the PC and assign it to a workgroup. N In the Network window move from Configuration to the Identification tab. N In the Computer name box, enter the name the PC is to appear under on the network. This name must be unique within the network. N In the Workgroup box, enter a name for the workgroup. This name must be the same for all the PCs on the network. N The Description box can be left empty.
Selecting the access control
Now you can define which access rights are to be assigned to resources you want to release. N In the Network window move from Identification to the Access control tab. Use the option Access control at release level to define that access to released files or printer is to be password protected. The option Access control at user level defines that access is permitted only for certain users or groups.
Sharing files and printers Setting the TCP/IP protocol
The TCP/IP protocol ensures that the PCs on the network can communicate with each other. This protocol requires certain settings which you will now make so that it can function smoothly. Checking the TCP/IP entry N In the Network window, check that there is a TCP/IP > entry for your network card or network adapter in the list of components. To do this, in the Network window, switch to the Configuration tab. If for example you are using a Gigaset PCI Card 54 as the wireless network adapter, the list must contain the entry TCP/IP > Siemens Gigaset PCI Card 54. If the entry for your network card or network adapter is there, please turn to page 64. N If the entry does not exist, click Add.
N Select as network component type Protocol and click Add. N Select in Manufacturers the entry Microsoft and in Network protocol the entry
TCP/IP before confirming with OK.
Setting the TCP/IP protocol N To do this, in the Network window, switch to the Configuration tab. N Select the TCP/IP > entry for your network card and click Properties.

This name must be identical for all the PCs on the network. Confirm this with next.
Sharing files and printers Checking the network settings
You will now see a screen in which you can check the settings you have made and make any changes you want.
N Click Back if you want to make any changes or click next, if you want to leave them

Sharing files and printers Accessing released printers from your PC
If there is a printer on your local network and it has been released, you can use it to print out your data. To do this you have to set it up on your PC as the network printer. This can be done as follows: N Open the printer manager with Printers and Faxes in the Start menu.
N Select Add printer. This opens the printer installation wizard. N Click next. N In the next window select Network printer or printer connected to another

computer.

N Click next again.
N Select Browse for a printer to look for the printer on the network. N Click next. This will open a screen in which you can search the network environment

for the printer.

N Select the printer you want and click next.
N Complete printer installation with Finish.
The newly installed printer will now appear in the printer list and can be used just like a local printer.
Making your own files and printers available (Windows 2000)
To release files or printers on a PC with Windows 2000 for other users on the network: 1. Install the network services (see below). 2. Select computer names and workgroup (see page 100). 3. Set TCP/IP protocol (see page 101). 4. Set up users (see page 103). 5. Release files and printer (see page 106).

Using files and printers on the network (Windows 2000)
You can use resources on your PC such as files and printers that have been made available by other PCs. To do this you have to make these resources available on your PC.
Accessing released drives or folders from your PC
You can access drives and folders released on other PCs in two different ways: N via the My NetworkPlaces of your PC (see page 75). You should choose this alternative if for example you want to copy files or folders from another PC to your own or vice versa. N by hooking on to your PC's file system (see page 112). You should choose this alternative if you want to work directly with the files or folders of the other PC. In this case, hook on an entire released drive or folder in your PC's file system and work with the files as if they were files on your PC.
Please bear in mind that drives or folders can be hooked on to several PCs at the same time and thus accessed by other users. Most applications (e. g. word processing software) lock files once they have been opened. This prevents inconsistent data pools. If you cannot open a file because it is locked, you will normally see a message to that effect.
