There are various ways in which you can set up the network with a Gigaset SE551 WLAN dsl/cable. You can
u set up a wired local network (Ethernet) and allow the connected PCs access to the

Internet (see page 9).

u set up a wireless local network (WLAN) and allow the connected PCs access to the
Internet (see page 10). page 12).
u set up a local network comprising wireless and wired network components (see
The Gigaset SE551 WLAN dsl/cable Wired local network (Ethernet)
In a wired local network, PCs communicate with one another via an Ethernet cable. When the Gigaset SE551 WLAN dsl/cable is used, it establishes the connection between the PCs. For this it has four Ethernet LAN ports for connecting four PCs. The PCs have to be equipped with a network socket (Ethernet). New PCs frequently already have this socket. For older PCs you need to install an Ethernet network card. The PC and the Ethernet LAN socket on the Gigaset SE551 WLAN dsl/cable are connected using an Ethernet cable (CAT5). There is one supplied. You can obtain additional Ethernet cables from your retailer. The Gigaset SE551 WLAN dsl/cable allows all PCs to access the Internet simultaneously. Gigaset SE551 WLAN dsl/cable

If you have already set a Password, enter the old Password in the Current password

field.

Enter a new password in the New password field, and repeat it in the Confirm new
password field. The Password can be up to 32 alphanumerical characters long. The SSID is case sensitive. Avoid proper names and all too obvious words. Mix letters and numbers together. Please remember: If you ever forget your Password you will have to reset your Gigaset SE551 WLAN dsl/cable (see page 18). Please bear in mind that this will restore all the settings to the factory configuration. No Password will be active either.
To go to the next step, click on Next >.
Before the wireless network components can communicate with each other, you must use the same SSID (Service Set Identifier). The default SSID for the Gigaset SE551 WLAN dsl/cable is ConnectionPoint. For security reasons you should change this SSID and deactivate SSID broadcast. If this option is enabled, the Gigaset SE551 WLAN dsl/cable will send the SSID in all data transmissions, and your Gigaset SE551 WLAN dsl/cable's SSID will be displayed on PCs that have a wireless network adapter. In this case unauthorised persons could use the SSID to gain access to your network.
Enter a character string of your choice in the SSID field. The SSID is case sensitive.
It can be up to 32 alphanumerical characters long. Make a note of the SSID. You will need this to register your PC. Please remember: The connection to the wireless network adapters will be broken until the new SSID has been entered in them as well. By default SSID broadcast is inactive. For security reasons you should not change this preconfiguration.
Click on Next > to proceed to the next step.
Setting security functions for the wireless network
In the next step you can set the encryption and authentication methods for your wireless network. Wireless networks are even more strongly exposed to the risk of eavesdropping than wired networks. With conventional network adapters an intruder only needs a device with a WLAN adapter (e.g. a Notebook or a PDA (Personal Digital Assistant)) with an appropriately configured network card in order to eavesdrop on every communication made via a nearby wireless LAN. The Gigaset SE551 WLAN dsl/cable makes use of effective encryption methods to prevent unauthorised eavesdropping as far as possible.
You can use the following security mechanisms:
u WPA2-PSK or WPA2-PSK / WPA-PSK (see below) u WEP encryption (Wired Equivalent Privacy, see page 39)
We recommend using WPA2-PSK if it is supported by all components in your wireless network. You will find further options for setting data encryption and authentication in the Advanced Settings menu (see page 74).
Security settings WPA2 / WPA with Pre-shared key (PSK)

You will then be returned to the Internet Connection screen. If necessary, you can now amend your entries.
If the test was successful, click on OK to apply the settings.
PPPoE pass-through If you activate the PPPoE pass-through function a PC in the network can connect to the Internet via its own connection ID. The router puts these connections through.
In the Advanced Settings Internet menu, select Internet Connection. Select the option On to activate PPPoE pass-through. Click on OK to apply the settings.
Using UPnP (Universal Plug and Play) PCs with UPnP (Universal Plug & Play) can offer their own network services and automatically use services offered on the network. Please remember: The PC must have Windows ME or Windows XP as its operating system. Check whether the UPnP function has been installed in your PC's operating system. It may be necessary to retrospectively install the UPnP components even on Windows XP or Windows ME systems. Please consult your PC's operating instructions. As soon as you have installed UPnP in the operating system of a PC and activated it on the router, applications on this PC (e.g. Microsoft Messenger) can communicate via the Internet without your needing to expressly authorise it. In this case, the router automatically implements port forwarding (Port Forwarding, see page 64), thereby facilitating communication via the Internet. You will see a symbol for your Gigaset SE551 WLAN dsl/cable on the task bar on the PC on which UPnP is installed. Windows XP systems will also include the icon under network connections. Clicking on this icon opens the Gigaset SE551 WLAN dsl/cable's configuration screens.
In the Advanced Settings Internet menu, select Internet Connection. Select UPnP.
Please remember: When the UPnP function is active, system applications can assign and use Ports on a PC. This can be a security risk.
Click on OK to apply the settings.
Configuring the Advanced Settings DNS server
DNS is a decentralised service which assigns PC names or Internet addresses (Domain names) and IP addresses to one another. A DNS server has to administer this information for each server or each LAN with an Internet connection. Normally your Internet provider provides you with a DNS server which makes this assignment when connection is made to the Internet. If necessary you can define the DNS server to be used for the Internet connections manually.

u If you deactivate the DHCP server, you will have to assign a static IP address for
the PCs using the network settings.
To activate the DHCP server, select On. If the DHCP server is active, you can define a Lease time. The Lease time determines
the period for which the PCs keep the IP address assigned to them without changing them. Please remember: If you select the Never expires option, the IP addresses are never changed. You must select this option if you want to make NAT or firewall settings using the IP addresses of the PCs, or else you must assign these PCs static IP addresses.
Define the range of IP addresses which the Gigaset SE551 WLAN dsl/cable should
use to automatically assign IP addresses to PCs. Define the First issued IP address and the Last issued IP address. field.
You can define the name of a domain (Windows workgroup) in the Domain name
Assigning static IP addresses to individual PCs
Even if you have activated the DHCP server you can still assign individual PCs a static IP address (e.g. if you are setting up these PCs for NAT functions).
Enter the MAC address and the name of the PC in the Device name field. Enter the IP address you wish to assign to the PC in the field below. Click on the Add button to add the entry to the list. Click on the Delete button to delete the entry from the list. Apply the settings by clicking OK.
Configuring wireless connections
If PCs are communicating wirelessly via the Gigaset SE551 WLAN dsl/cable, you should also take steps to enhance the security of your wireless network. You make this configuration via the Advanced Settings Wireless Network menu. Here you can

Instructions for setting up a printer on the PC
Once you have installed the printer port you still cannot start printing. The printer port is nothing more than an additional interface on your PC, comparable with the USB port. It means that any printer you install on this port is also regarded as a local printer even though it is located in the network and possibly remote from you. You still need to connect and configure the printer to this port.
Connect the printer to the USB interface on your Gigaset SE551 WLAN dsl/cable.
The printer is installed in the same way as any other printer:
Go through Start Settings Printer and click on New Printer. In the window that opens, click on Next. Proceed as instructed by the printer installation wizard. Please note:
In the window in which you are prompted to specify the location of the printer you should select Local Printer (usually the default setting).
Then click on Next. Continue to install the printer. Select your printer and click on Next. When the window appears in which you are prompted to enter the type of connection, double click on the port name Gigaset_Druckerport.
Then continue to install the printer and finish the installation.

Glossary

Access Point An Access Point, such as the Gigaset SE551 WLAN dsl/cable, is the centre of a wireless local network (WLAN). It handles the connection of the wireless linked network components and regulates the data traffic in the wireless network. The Access Point also serves as an 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 Ad-hoc mode describes wireless local networks (WLANs) in which the network components set up a spontaneous network without an Access Point e.g. several Notebooks in a conference. All the network components are peers. They must have a wireless Network adapter. Auto Connect Auto Connect means that applications such as Web browser, Messenger and Email automatically open an Internet connection 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 save call charges. 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.

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 Infrastructure Network
The infrastructure mode is used to connect wireless and wired networks with each other. In addition to the mobile stations, the infrastructure mode needs an access point, also known as a base station. In infrastructure mode, the stations on the network always communicate with each other via an access point. Unlike the ad-hoc mode, the access point sets up the wireless network on a permanent basis, and every station that wants to be part of the wireless network has to register with the access point before it is allowed to exchange data. Using an access point also extends the range of the wireless network. The access point establishes the connection from the mobile stations of a wireless network to a wired LAN (Ethernet) or to the Internet. In this case, this is referred to the router functionality of the device. The access point sends data packets that are not addressed to stations in its network "outside" and passes data packets coming from "outside" to the appropriate station in its network. The Gigaset SE551 WLAN dsl/cable is such an access point. You can use it for connecting
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.

How to make the printer connected to another PC available on your PC is described in Chapter ""Using released files and printers" on page 49": for Windows XP from page 55 for Windows 2000 from page 61 for Windows 98, 98 SE, ME from page 69 u Controlled access to the Internet You want to prevent users accessing particular Internet services or children having access to any Internet pages at all. With the Gigaset Routers you can completely isolate PCs from the Internet. restrict access to Internet services, prevent access to particular web domains or Internet sites. u Protecting local networks from unauthorised access To protect your network from unauthorised access, you can for example set up access control for wireless users, set data encryption (only on wireless networks). u Running games, conferences and telephony via the Internet The Gigaset SE551 WLAN dsl/cable comes programmed with a comprehensive firewall functionality that protects your local network against unauthorized access from the Internet. Some applications however, such as games, video conferences, Internet telephony etc., require the possibility of external access from the Internet to local applications. The normal configuration of the router does not permit "external" access and supports only those Internet applications that do not need more than one connection (e.g. file transfer, email.).
u Making your own server available on the Internet
Advanced Internet users might like to set up a Web server of their own so that they can have their own home page or other offerings on the Internet. This requires a particular configuration for the Gigaset SE551 WLAN dsl/cable. You will find information regarding the configuration of the four above-named functions of your Gigaset SE551 WLAN dsl/cable in the device's user guide.

Releasing files and printers for shared use
A very common function of local networks is to allow the shared use of files and printers. Users can access from any PC on the network those files made available by another PC on that network, or they can print their files via a printer administered on another PC.

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:

of your choice. From now on, your printer will be available to all the other users on the network under this name.

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
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).

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

Now open the desktop. The remote drive is now available as the network drive. You
Open the printer manager with Start Settings Printers.
Double-click the Add printer icon. This opens the printer installation wizard. Click Next. In the next window select Network printer. Click Next again.
Enter the name under which the printer was released for the network. To do this Select the printer you want and click OK.
click Browse. This will open a screen in which you can search the network environment for the printer.
The printer will now be displayed. Click Next.
Now enter a name for the printer on your PC.
Click Next. You can now print a test page if you want. This will show you whether the printer is
functioning properly on the network.
Click Finish. Windows will now need some driver files. You will be prompted to insert your
Windows CD in the CD drive. Insert the CD and click OK.
Once the driver files have been successfully installed, a test page will be printed. The newly installed printer will now appear in the printer list and can be used just

like a local printer.

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.

Private IP addresses

You can determine your own private IP addresses for the PCs in your local network. To do this use addresses from an address block reserved for private use. This is the address block 192.168.0.0 192.168.255.254 Example: PC 1: 192.168.15.1 PC 2: 192.168.15.2 etc. Please note: The subnet mask used must be 255.255.255.0. This means that the first three address segments for all network components (including the router) must be identical.

u Correct is e. g.:

Router address: 192.168.2.1 PC 1: 192.168.2.12 PC 2: 192.168.2.60.
u Incorrect would be e. g.:
Router address: 192.168.2.1 PC 1: 192.168.3.2 PC 2: 192.168.4.3

Windows 98

To set an IP address for your PC:
Select Start Settings Control Panel. Double-click the Network icon. In the Network window, select the TCP/IP entry for your network card or network

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.

DHCP Dynamic Host Configuration Protocol DHCP handles the automatic assignment of IP addresses to network components. It was developed because in large networks especially the Internet the defining of IP addresses is very complex as participants frequently move, drop out or new ones join. A DHCP Server automatically assigns the connected network components (DHCP Clients) Dynamic IP addresses from a defined IP address pool thus saving a great deal of configuration work. It also allows address pools to be used more effectively: Since not all participants are on the network at the same time, the same IP address can be assigned to different network components in succession as and when required. The Gigaset SE551 WLAN dsl/cable includes a DHCP Server and so it can automatically assign IP addresses for the PCs on its local network. You can define for a particular PC that its IP address will never change. DHCP Server See DHCP DMZ Demilitarised Zone DMZ describes a part of a network that is outside the Firewall. A DMZ is so to speak set up between a network you want to protect (e. g. a LAN) and an insecure network (e. g. the Internet). A DMZ is useful if you want to offer Server services on the Internet which for security reasons are not to be run from behind the firewall or if Internet applications do not work properly behind a firewall. A DMZ permits unrestricted access from the Internet to only one or a few network components, while the other network components remain secure behind the firewall. DNS Domain name DNS permits the assignment of IP addresses to computers or Domain names that are easier to remember. A DNS Server has to administer this information for each LAN with an Internet connection. As soon as a page on the Internet is called up, the browser obtains the corresponding IP address from the DNS Server so that it can establish the connection. On the Internet the assignment of Domain names to IP addresses follows a hierarchical system. A local PC only knows the address of the local Name Server. This in turn knows all the addresses of the computers on the local network and the next higher Name Server, which again knows addresses on its network and that of the next Name Server. DNS Server See DNS Domain name The Domain name is the reference to one or more Web Servers on the Internet. The Domain name is mapped via the DNS service to the corresponding IP address.
DSL Digital Subscriber Line DSL is a data transmission technique in which a connection to the Internet can be run at 1.5 Mbps over normal telephone lines. A DSL connection is provided by an Internet Service Provider. It requires a DSL modem. Dynamic IP address A dynamic IP address is assigned to a network component automatically via DHCP. This means that the IP address of a network component can change with every login or at certain intervals. See also: Static IP address DynDNS Dynamic DNS Domain Name Service (DNS) is used to assign Domain names and IP addresss. For Dynamic IP addresss this service is now enhanced with the so-called Dynamic DNS (DynDNS). This permits the use of a PC with a changing IP address as a Server on the Internet. DynDNS ensures that a service on the Internet can always be addressed under the same Domain name regardless of the current IP address. Encryption Encryption protects confidential information against unauthorised access. With an encryption system data packets can be sent securely over a network. The Gigaset SE551 WLAN dsl/cable uses WEP encryption for secure data transmission over wireless networks. Ethernet Ethernet is a network technology for local networks (LAN) defined by IEEE as Standard IEEE 802.3. Ethernet uses a base band cable with a transmission rate of 10 or 100 Mbps. Firewall Firewalls are used by network operators as protection against unauthorised external access. This involves a whole bundle of hardware and software actions and technologies that control the data flow between the private network to be protected and an unprotected network such as the Internet. See also: NAT Flat rate Flat rate is a particular billing system for Internet connections. The Internet Service Provider charges a monthly fee regardless of the duration and number of logins. Full duplex Data transmission mode in which data can be sent and received at the same time. See also: Half duplex

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.
