This Gateway allows you to set up a network with your PCs and share your Internet connection. The Gateway does this by connecting to your ADSL line, and using the Gateway's Ethernet ports to connect your PCs; it's like each PC is connected directly to the Internet. This way, you have an Ethernet network where you have several PCs utilizing one Internet connection simultaneously. Plus, if you add a Linksys wireless PC Card, it can be used as an Access Point and the Gateway can bridge your Ethernet network with your wireless PCs. The PCs that you connect to the Gateway's four LAN ports, when properly configured, create a LAN, or Local Area Network. They are connected with an Ethernet cable plugged into your computer's Ethernet adapter at one end and into one of the Gateway's LAN ports (numbered from one to four) at the other end. The term "Ethernet" is used to refer to your network accessories, such as cables and adapters, because Ethernet refers to the type of network that you are setting up. Ethernet refers to the accessories that transfer computer data from 10Mbps to 100Mbps (speeds used by network devices.) The Gateway allows you to share your ADSL connection using a built-in ADSL modem, and can plug directly into your ADSL-enabled wall jack (DSL service line). The PCs that are connected to the Gateway share this connection.

The other, public side is the Internet, or the Wide Area Network (WAN), outside of your home or office. The Gateway's firewall (NAT) protects your network of PCs so users on the public, Internet side cannot "see" your PCs. This is how your LAN, or network, remains private. The Gateway protects your network by inspecting the first packet coming in through the WAN port before delivery to the final destination on the LAN port. The Gateway inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side. IP Addresses What's an IP Address? IP stands for Internet Protocol. Every device on an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its "location," or address, on the network. This applies to both the WAN and LAN connections. There are two ways of assigning an IP address to your network devices. Static IP Addresses A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses are commonly used with network devices such as server PCs or print servers. When using the Gateway to share your ADSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Gateway. You can get the information from your ISP. Note: Since the Gateway is a device that connects two networks, it needs two IP addresses--one for the LAN side, and one for the WAN side. In this U ...
