Firewall

The firewall functions of the Gigaset SE551 WLAN dsl/cable include various security functions for your local network. You can:
u protect your network against hacker attacks (see below), u block individual PCs' access to selected services or Internet sites (see page 56) or
restrict them by means of a schedule rule (see page 59). The firewall functions for Gigaset SE551 WLAN dsl/cable are activated and configured in the factory. If you wish to deactivate the firewall, carry out the following steps:

Select a Schedule rule: The default setting is Always. You can create more Enter a name for the Comment of the access rule. Enter a name for the access rule in the Comment field. Define the Access level.
You can apply Deny access to the Internet, Allow web browsing with URL filter, Allow web browsing or make user-defined settings. If you select the option Allow web browsing with URL filter, you must define the URL filter (see page 59). If you select Custom, you have the following options:
In Filtering mode, determine whether the services you select are to be allowed or blocked. Select the Services you wish to allow or block. Select the Protocol and enter the appropriate Port (a single port number, several individual port numbers separated by commas, port blocks consisting of two port numbers separated by a dash, or any combination of these, e.g. 80,90-140,180). The displayed Comment assists you to identify different services. Activate the Filter option to use the service concerned for the service filter. You can also select services from the Predefined applications list. Click on Delete to delete an entry. Click on Add to create a new entry with the entered data or for the selected, predefined application.
Schedule Rules If you have set up an access rule (see page 57) for certain services in the Internet. you can control it by means of a schedule rule. A schedule rule determines the period for which a defined access control is active. You can define several rules. A rule takes effect when you select Access Rules in the menu and activate it.
In the Access Control field under Schedule Rules, click on Edit.
Assign a name to the new rule under Comment. This name will then appear in the
selection list on the screen for the menu entry Access Rules. Click on Add to define a new rule. Select the day of the week from the list or else the option Every day. Enter the time for the rule to Begin and End. Click OK to apply the settings.
URL filter The URL filter allows you to block access to certain Internet sites or Internet domains or to limit access to certain Internet sites. Once you have entered the relevant URLs you can then create access rules that apply the URL filter for the selected clients in your network.
In the Advanced Settings Internet Firewall menu, select Access Control.
Select Filtering mode, i.e. whether you wish to allow or block access to the URLs in

the list.

Enter the required URL in the field. Click on Delete to delete an entry. Click on Add to create a new entry. Click OK to apply the settings.
Setting up the NAT function
Your Gigaset SE551 WLAN dsl/cable 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 feature 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 e-mails, 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 a particular protocol (TCP or UDP). 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 users on the Internet to the user on the local network. These applications cannot work if Network Address Translation (NAT) has been activated. Using port forwarding (the forwarding of requests to particular ports) you make the router forward requests from the Internet for a certain service, e.g a game, to the appropriate port or ports on the PC on which the game is running. Port triggering is a specific variant of port forwarding. Unlike port forwarding, in this case the Gigaset SE551 WLAN dsl/cable forwards data from the set port block to the PC which has previously sent data to the Internet via a certain port (trigger port). This means that approval for the data transfer is not tied to one specific PC in your network, but only to the port numbers of the required Internet service. Where configuration is concerned, this means:
u You have to define a so-called trigger port for the application and also the protocol
(TCP or UDP) that this port uses. Then you assign to this trigger port the public ports that have to be opened for the application. u The router checks all outgoing data for the port number and protocol. If it recognises a match of port and protocol to a defined trigger port, then it will open the assigned public ports and notes the IP address of the PC that sent the data. If data comes back from the Internet via one of these public ports, it allows the data through and directs it to the right PC. A trigger event always comes from a PC within the local network. If a trigger port is addressed from outside, it is simply ignored by the router.

Please remember:

u An application that is configured for port triggering can only be run by one user in
the local network at a time.
u As long as the public ports are open, they can be used by unauthorised persons to
gain access to a PC in the local network.
When the Gigaset SE551 WLAN dsl/cable is supplied, the NAT function (Network Address Translation) is activated, i.e. all IP addresses of PCs in the local network are converted to the router's public IP address when accessing the Internet. You can use the NAT settings for the Gigaset SE551 WLAN dsl/cable to
u set up port triggering for special applications (see page 63), u set up the Gigaset SE551 WLAN dsl/cable as a virtual server by configuring Port For-

warding (see page 64),

u open the firewall for selected PCs (see page 65).
Please remember: For the functions described below you must make sure that the IP addresses of the PCs do not change. If the IP addresses of the PCs are assigned via the DHCP server of the Gigaset SE551 WLAN dsl/cable, you must select the option Never expires (see page 70) for the settings on the Local Network screen for Lease time or assign static IP addresses for the PCs. You can activate or deactivate the NAT function (default setting: NAT function is activated).
In the Advanced Settings Internet menu, select Address Translation (NAT) and
select the required option.
Configuring the Advanced Settings Port Triggering
If you configure Port Triggering for a certain application, determine a so-called trigger port and the protocol (TCP or UDP) this port uses. Then you assign to this trigger port the public ports that have to be opened for the application. You can select known Internet services for this or assign ports or blocks of ports manually.
To set up port triggering for a service, in the Address Translation (NAT) menu,

select Port Triggering.

Select the required application from the Predefined applications list. Click the Add button. The data for the required service is entered on the screen. Select the option in the Enabled column.
If the application you require is not in the list, then you must enter the relevant data on the screen manually:
Local protocol: Select the protocol that is to be monitored for outgoing traffic. Local port: Enter the port that is to be monitored for outgoing traffic. Public protocol: Select the protocol that is to be allowed for incoming data traffic. Public port: Enter the port that is to be opened for incoming traffic. Note: You can enter a single port number, several individual port numbers separated by commas, port blocks consisting of two port numbers separated by a dash, or any combination of these, e.g. 80,90-140,180).
Comment: Enter a description to help you identify different entries.

Select the Off option to deactivate SSID broadcast.
Transmission mode This function is only shown in the window if the Super G transmission mode is deactivated (see page 73). The standard IEEE 802.11g permits data transfer up to 54 Mbit/s, IEEE 802.11b up to 11 Mbit/s. For the best possible data transfer rates in your network select IEEE 802.11g only. To operate clients with older wireless network adapters in your network, select IEEE 802.11b/g (mixed).
Select the required transmission mode for your wireless network. Select the required sending power for your device.

Sending power

We recommend that you select a sending power with a range to suit the spatial environment of your local network. A much greater range makes it easier to eavesdrop on your wireless data transmission.
Super G (108 Mbit/s) With the aid of channel bundling, the Super G transmission mode enables wireless data transfer up to 108 Mbps. The channel for wireless data transfer cannot be changed. You can only use Super G if this function is supported by at least one client in your wireless network. For the best possible data transfer rates, all clients in your LAN should support Super G. Please remember: If you activate Super G as the transmission mode, but it is not supported by all components in your wireless network, then for technical reasons the transfer rate in the network may be significantly lower than the possible maximum of 108 Mbit/s.
Select the mode for using Super G (108 Mbit/s) for your wireless network to increase the data transmission speed. You have a choice of two modes. Static: Wireless transmission is at a rate of just 108 Mbps. Clients that do not support this speed cannot connect to Access Point. Dynamic: If you select this transmission mode, the router accepts subscribers that communicate at different transfer rates and adjusts to the slowest client in the network. menu.
If you do not wish to use Super G (108 Mbit/s), select Disabled in the selection
XR (extended range) Activating XR enables data transfer even in the peripheral areas of your wireless network, albeit at very low data transfer rates. Conversion to XR mode occurs automatically when the signal is weak enough and if the partner station is also XR capable.
Activate or deactivate XR for your wireless network to increase the range. Click on OK to apply the settings.
Configuring the Advanced Settings Setting wireless security
If you are sending data over wireless channels, we recommend that you activate encryption (WEP or WPA) on your wireless network components. WPA offers greater security than WEP. We therefore recommend that you choose WPA encryption if it is supported by all components in your wireless network. WPA is a more advanced procedure than WEP for protecting wireless networks. Dynamic keys based on TKIP (Temporal Key Integration Protocol) offer increased security. The new standard WPA2 is based on AES. WPA also supports the use of an authentication server.

In the Security field, select the option WEP.
Select the Authentication type:
Select Shared to require that each client logs in to the network with a specified key. Select Open to permit data transfer within your wireless network without the need for a key. You can choose either the standard 64 bit key or the more robust 128 bit key for encryption. The keys are generated in hexadecimal or in ASCII format. You must use the same keys for encryption and decryption for both the Gigaset SE551 WLAN dsl/cable and all your wireless network adapters.
generated automatically by means of a Passphrase. Generating the key by means of a Passphrase keys are generated.
Enter a Passphrase (up to 32 characters) and confirm it by entering it again. Four Select one of the four keys as Default key.

Repeater A repeater extends the range of a wireless local area network by relaying data from the Access Point to additional PCs or Network adapter. Roaming Roaming extends the range of a wireless LAN by using several Access Points that use the same SSID and the same radio channel and are linked via Ethernet. The PCs in the network can switch dynamically between several Access Points without losing the existing network connection. Router A router directs data packets from one local area network (LAN) to another via the fastest route. A router makes it possible to connect networks that have 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). The term "server" is often used to refer to a computer or PC. However it can also mean an application that provides a particular service such as DNS or a Web service. SIP Session Initiation Protocol SIP is a standard for data transfer in Internet telephony (VoIP). It describes how a call is carried over the data network and which components plus which transport and signalling protocols are involved. 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 Provider provides you with access to an SMTP server. SNMP Simple Network Management Protocol The SNMP Protocol is part of the TCP/IP protocol family. It provides a simple procedure for administering the network based on a system of shared information for management data and network management messages (known as traps) and reports the occurrence of events within the monitored network (e.g. an alarm message or notification of configuration changes).
SSID Service Set Identifier The SSID is used to identify the stations in a wireless network (WLAN). All wireless network components with the same SSID form a common network. The SSID can be assigned by the network operator. Static IP address A static IP address is assigned to a network component manually during network configuration. Unlike a Dynamic IP address, a static (fixed) IP address never changes. Subnet A subnet divides a network into smaller units. Subnet mask The subnet mask determines how parts of the IP addresses of a network represent the network number and how many the computer number. The subnet mask in a network 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 is an extension of IEEE 802.11g. Channel bundling doubles the maximum transfer rate to 108 Mbps. Unlike other technologies (e.g. 125 Mbps technology) which work by compressing data, here the transfer rate is actually doubled. If data is already compressed (ZIP, RAR, MP3, MPEG etc.) data compression offers no significant improvements. Switch A switch, like a Hub, is an element used to link different network segments or components. Unlike a Hub however, the Switch has its own intelligence that enables it to forward packets to only the subnet 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 forms the basis for every computer-tocomputer 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. 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 on another network component. The Gigaset SE551 WLAN dsl/cable can be configured as a virtual server. It will then direct incoming calls for a service via Port Forwarding directly to the appropriate Port of the network component in question. VoIP Voice over IP See Internet telephony 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 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. WLAN Wireless LAN Wireless LANs enable network components to communicate with 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 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 the security provided by WEP. WPA uses complex procedures to generate keys, such as TKIP (Temporal Key Integrity Protocol). In addition, WPA can use an authentication server (e.g. a RADIUS server) to increase security. WPA-PSK WPA Pre-shared 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 (Rekey Interval). XR eXtended Range XR technology increases a WLAN's range and ensures better coverage of the area in the home or office network. When activated at the Access Point, this function can considerably increase the range to the network adapters, although at the expense of the data transfer rate.

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 In the examples we assume that the Gigaset network components have been
installed and configured as per the corresponding operating instructions. rights.

Local networks with Gigaset products
You can use Siemens Gigaset WLAN devices to set up a local network, e.g. a home network. All the PCs in this network can communicate with each other and have access to the Internet. The PCs can run on Windows 98, Windows ME, Windows 2000 or Windows XP. Gigaset Routers e.g. the Gigaset SE551/WLAN dsl/cable have an interface to enable Internet access, so that you can connect a DSL or cable modem for Internet access (WAN interface).
Gigaset SE551 WLAN dsl/cable Windows ME

Modem Windows 2000

local network

Windows XP

Windows 98 SE

You can set up the network in a number of ways. You can

u Use a Gigaset SE551 WLAN dsl/cable to set up a wired local network (see page 5). u Use the Gigaset SE551 WLAN dsl/cable to set up a local network comprising wireless
and wired network components (see page 8).
u Use the wireless network adapters Gigaset PC Card 108, a Gigaset USB Adapter 108
or a Gigaset USB Stick 108 to set up a wireless network without routers, i.e. connect PCs directly with each other (see page 6), or connect PCs to a Gigaset SE551 WLAN dsl/cable (see page 7). u Use one or more Gigaset WLAN Repeaters to extend the range of your wireless local network (see page 10).
Introduction Wired local network (Ethernet)
In a wired local network the PCs are linked via an Ethernet cable. The Siemens Gigaset SE551 WLAN dsl/cable has four Ethernet LAN ports for connecting four PCs. The PCs must have an Ethernet network adapter that is connected via an Ethernet cable to a LAN port on the router. New PCs frequently come supplied with such a socket. You can buy Ethernet cables (CAT-5) from specialist retailers.

Ethernet

The WAN interface on the Gigaset SE551 WLAN dsl/cable allows all PCs in the network to access the Internet simultaneously. To use this feature you will need the access data from an Internet Service Provider, e. g. T-Online.
Introduction Wireless local network (WLAN)
In a wireless local network (WLAN), the PCs are linked to each other via a wireless connection. The PCs must be equipped with a wireless network adapter (e.g. the Gigaset PC Card 108 or Gigaset USB Adapter). We generally differentiate between two types of wireless networks:
u ad-hoc mode u infrastructure mode

Ad-hoc network

Ad-hoc networking is a new concept in network communications that is rapidly gaining in popularity. Ad-hoc networks do not have any fixed network infrastructure. The mobile network components that communicate with each other directly and without wire connections form the network "ad-hoc", i.e. as and when required. All the stations on the network have the same rights. Ad-hoc networks are used wherever communications networks have to be set up quickly and without any existing network infrastructure and where the participants are on the move. An ad-hoc network is a wireless network set up without using a router.

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.

Introduction Roaming

In a wireless network with several repeaters, roaming allows the connected subscribers (PCs) to move freely between the different repeaters without breaking their contact with the access point. As soon as there is a risk of losing contact, the PC automatically searches for another repeater with a stronger signal. This allows you to set up wireless networks that cover a much larger area than would be possible with just a single access point (and a single additional repeater). Multiple repeaters also allow more subscribers to be served simultaneously. The main area of application for WLANs with roaming is on large company sites and in universities.

Repeater

Access point
In a roaming network, all the users must use the same SSID and encryption. The access point must be connected to a wired network (Ethernet). For details, refer to the operating instructions on the CD supplied.

Possible uses

No matter which type of network you have opted for, Gigaset products for local networks offer a wealth of uses.

u Shared use of files

You can use your Gigaset SE551 WLAN dsl/cable or a PC in the network as a file server. All central data are then stored in a bulk memory connected directly to the USB interface on your Gigaset SE551 WLAN dsl/cable or in the data system of a PC in the network. 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 connect a bulk memory to the Gigaset SE551 WLAN dsl/cable and use it in the network is described in the device's user guide. How to release files on one PC for access to users on other PCs is described in Chapter "Releasing files and printers for shared use": for Windows XP from page 21 for Windows 2000 from page 32 for Windows 98, 98 SE, ME from page 46 How to make released files on other PCs available on your PC is described in Chapter "Using released files and printers": for Windows XP from page 53 for Windows 2000 from page 58 for Windows 98, 98 SE, ME from page 66 u Shared use of printers Printers can be made available to PCs in the network in two ways: directly via the USB interface on your Gigaset SE551 WLAN dsl/cable via the PC on the network to which the printer is connected All users can print their files at these printers. Being directly connected to the Gigaset SE551 WLAN dsl/cable offers the advantage that the printer is always available without having to ensure that a specific PC is switched on. How to connect a printer to the Gigaset SE551 WLAN dsl/cable and use it in the network is described in the device's user guide. How to release a printer on one PC is described in Chapter "Releasing files and printers for shared use": for Windows XP from page 23 for Windows 2000 from page 36 for Windows 98, 98 SE, ME from page 47

File Server

This chapter describes what steps you must carry out to release files and printers for network usage. It assumes that the network cards or wireless network adapters have already been installed in the PCs and that the PCs are either connected via a router or directly via an ad-hoc network. The following steps are necessary before files and printers can be shared on the network:
u The network has to be set up on all the computers. The Internet protocol (TCP/IP) has
to have been set as the connection method.
u All PCs have to have been assigned to the same network (workgroup). u Users who want to make their files or printer available have to release them on

their PC.

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.

Using released files and printers
This chapter describes the steps for using files or printers that are shared on the network on your system. It assumes that the network cards or wireless network adapters are installed in your PC and that the PCs are either connected via a router or directly via an ad-hoc network. Network configuration, release and use differ depending on the Windows operating system used. The following table provides an overview of where you can find the relevant information in this chapter. Windows XP Setting up user names Using files on other PCs Using printers on other PCs page 50 page 53 page 55 Windows 2000 page 58 page 58 page 61 Windows 98 page 63 page 66 page 69

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.

Defining IP addresses

The IP address is used for the unique identification of a network component. You can define IP addresses as static or dynamic. This is done while defining the PC network configuration. In many cases the IP addresses are defined as dynamic and so can change every time you log in to the network. For some applications however you have to make sure that the PCs always have the same IP address. If you opted for automatic assignment of IP addresses during installation, you can change this via the PC network configuration. Network configuration differs depending on the Windows operating system you are using. Below you will find the procedure for Windows 98 from page 73, for Windows XP from page 77 and for Windows 2000 from page 80.

Click Start Control Panel. Select Network and Internet Connections and then click the Network Connections icon.
Double-click the LAN connection with which you are connected to the router.
In the General tab click Properties.
Select Internet Protocol (TCP/IP) and click Properties.
Select Use the following IP address. Enter the IP address for the PC in the IP address box. Please bear in mind the information on page 72. Note: If your PC has already been configured with a static IP address and you now need a dynamic one, select Obtain an IP address automatically. Then no further information will be required.
Enter the subnet mask 255.255.255.0 in the Subnet mask box. Enter the IP address for the router in the Standard-Gateway box.
Select Use the following DNS server addresses.
Enter the IP address for the router in the Preferred DNS server box. Click OK or Cancel to close each window. Restart your network.

Windows 2000

To set a static IP address for your PC:
Click Start Settings Control Panel. Double click the Network and Dial-up Connections icon and then Local Area Connection.
Note: A gateway acts as a bridge between two networks with a different architecture. In our case this is the Gigaset Router between the local TCP/IP network and the WAN.
Enter the IP address for the router in the Preferred DNS server box. Close this and the next window with OK. Restart your network.

Glossary

Access point An Access Point, such as the Gigaset SE551 WLAN dsl/cable, is the heart of a wireless local network (WLAN). It ensures the connecting of network components linked by wire and handles the data traffic in the wireless network. The Access Point is also the interface to other networks, e. g. an existing Ethernet LAN or via a modem to the Internet. The operating mode of wireless networks with an Access Point is called Infrastructure mode. Ad-hoc mode The Ad-hoc mode is a way operating wireless local networks (WLAN) in which the network components set up a spontaneous network without an Access point, e. g. several Notebooks used in a conference. All the network components have equal rights. They must be fitted with a wireless Network adapter. Auto-Reconnect Auto-Reconnect means that applications such as Web Browser, Messenger and E-Mail automatically open a connection to the Internet when they are launched. This can lead to high charges if you are not using Flat rate. This function can be deactivated at the Gigaset SE551 WLAN dsl/cable to reduce costs. Bridge A Bridge connects several network segments to form a joint network, e. g. to make a TCP/IP network. The segments can have different physical characteristics, e. g. different connections such as Ethernet and wireless LANs. Linking individual segments via Bridges allows local networks of practically unlimited size. See also: Switch, Hub, Router, Gateway Broadcast A Broadcast is a data packet not directed to a particular recipient but to all the network components on the network. The Gigaset SE551 WLAN dsl/cable does not pass broadcast packets on; they always remain within the local network (LAN) it administers. BSSID Basic Service Set ID BSSID permits unique differentiation of one wireless network (WLAN) from another. In Infrastructure mode the BSSID is the MAC address of the Access point. In wireless networks in Ad-hoc mode the BSSID is the MAC address of any one of the participants. Client A Client is an application that requests a service from a Server. For example, an HTTP Client on a PC in a local network requests data, i.e. Web pages, from an HTTP Server on the Internet. Frequently the network component (e. g. the PC) on which the Client application is running is also called a Client.

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.

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.
