Here it complies with Standard IEEE 802.11g ­ i.e. the router can be used together with products of several other manufacturers. Using a Gigaset SE505 dsl/cable makes it easy to set up a network at home or in small offices. For example, users can exchange data or share resources on the network, such as a file server or printer. With the Gigaset devices for wireless networks you can operate a LAN ­ as envisaged in Standard IEEE 802.11 ­ in Ad-hoc mode and in Infrastructure mode. The Gigaset SE505 dsl/cable supports DHCP for dynamic IP configuration of the local network and DNS for Domain name mapping. N Internet access The Gigaset SE505 dsl/cable permits Internet access via a WAN socket with a transmission speed of 10 or 100 Mbps. You can connect a DSL or cable modem to this socket. ­ Since many DSL providers permit communication with end users with the PPPoE protocol, the Gigaset SE505 dsl/cable has an integrated Client for this protocol, so you no longer have to install this service on your computer. ­ Shared IP address If your Internet Service Provider permits this, the Gigaset SE505 dsl/cable can make do with a single IP address for up to 253 users. Several users on your network can then surf the Internet at the same time using only one Internet Service Provider account. N Virtual Private Network (VPN) The Gigaset SE505 dsl/cable supports three of the most common Protocols for setting up a Virtual Private Network: PPTP, L2TP and IPSec. This allows you to connect devices at different locations via the Internet securely, if your Internet Service Provider offers this service. 6 The Gigaset SE505 dsl/cable N Protection against unauthorised access from the Internet The Gigaset SE505 dsl/cable offers comprehensive security measures such as: ­ Firewall All the PC's in the local network use the router's Public IP address for their Internet connections, which makes them 'invisible' on the Internet. The router only allows access from the Internet if it has been requested from the local network. ­ With its firewall, the Gigaset SE505 dsl/cable also offers comprehensive protection from attack by hackers. N Offering your own services on the Internet ­ If you want to offer your own services on the Internet, you can configure the router as a virtual server without permitting further access to the local network. ­ DMZ This allows you to release a PC on your local network for unrestricted access from the Internet without compromising the security of the other PC's. N Restricting Internet access You can configure the Gigaset SE505 dsl/cable so that Internet access is blocked or limited for various users. You can also use filters to control which PC's are able to use which Internet services, and you can disable access to certain Internet domains and sites.

The WLAN/ACT LED lights up, indicating that the wireless interface of the Gigaset SE505 dsl/cable has been activated. The wireless link to the PC's connected via a wireless network adapter will be established automatically if their network adapters have been configured with the same SSID as the router (see page 15). It can take a few seconds for the wireless connection to be established. The WLAN/LINK LED flashes to indicate when devices are connected with the wireless interface. If this is not the case, please turn to "Fault tracing" on page 105. 17 Configuring the local network Configuring the local network Once you have set up the hardware and connected all the devices, you have to configure the network settings of all the PC's that will communicate with each other via the Gigaset SE505 dsl/cable. The LAN is set up as a TCP/IP network. You will have to make certain choices during the configuration procedure. The most important decision is whether you want to use the router's DHCP service or not. The router uses DHCP (Dynamic Host Configuration Protocol) to assign Dynamic IP addresses for the network components, i.e. it automatically assigns a PC that logs in an IP address from a defined address block. The next time the PC logs on it may well be assigned a different IP address. How to configure the router's dynamic address assignment is described on page 76 of the section "LAN Configuration". In this chapter we assume that you will use the router's DHCP service. This is also the router's default setting. In many cases however it is advisable to assign Static (fixed) IP addresses, e.g. if you wish to run a wireless network in Ad-hoc mode. How to assign fixed IP addresses is described in "Practical Tips and Configuration Examples" on the CD supplied. If your network has already been set up you can read on from page 45 in the chapter "The user interface". The network configuration varies depending on the Windows operating system you are using. You will find the procedure described below for Windows 98 from page 19, for Windows XP from page 28 and for Windows 2000 from page 36. Have your Windows Installation CD to hand. You may be prompted to insert it. i The Windows user interfaces depicted in this guide may differ from those on your screen because of the settings you have made. The illustrations always reflect the state after immediate installation. 18 Configuring the local network Network configuration for Windows 98, 98 SE, ME To integrate a PC with Windows 98, 98 SE or ME in a local network, you must carry out the following steps: 1. Set up the PC as the Client for Microsoft Networks (see below). 2. Select computer names and workgroup (see page 20). 3. Install the TCP/IP protocol (see page 21). 4. Make TCP/IP protocol settings (see page 22). 5. Deactivate the http proxy (see page 26). 6. Synchronise the TCP/IP settings to the Gigaset SE505 dsl/cable (see page 27). Setting up a PC as a Client for Microsoft Networks Before the PC's on your network can work together, you have to configure them as Microsoft Network Clients. This is done as follows: N Click on Start ­ Settings ­ Control Panel. N Double click on the Network icon and open the Configuration tab in the Network window. N Check whether the list of components contains the entry Client for Microsoft Networks. N If it is not there click on Add. N Select Client as the network component type and click on Add. 19
