The Router is the perfect solution for connecting a network of PCs to a high-speed broadband Internet connection and to an Ethernet network backbone. Configurable as a DHCP server for your network, the Router is the only visible network device on the Internet. The Router also serves as your Internet NAT firewall, protecting your network's PCs from being accessed by external users. All incoming data packets are monitored and filtered. The Router can also be configured to block internal users' access to the Internet with IP filtering, as well as to play Internet games, videoconference, and much more. Plus, the Router supports Universal Plug and Play (UPnP), which allows Windows XP to automatically configure the Router for various Internet applications, such as videoconferencing and gaming--making the Router a snap to use. Now all of your PCs can enjoy lightning-fast broadband Internet connections and share internal network data. Link them all together and network faster than you ever thought possible.

This is how your LAN, or network, remains private. The Router 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 Router 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. Remember that the Router's ports connect to two sides: your 10/100 LAN port(s) and the Internet WAN port. The LAN port(s) transmit data at 10 Mbps or 100 Mbps, whereas the broadband port, or WAN port, transmits data at 10 Mbps. 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. Note: Since the Router 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 User Guide, you'll see references to the "WAN IP address" and the "LAN IP address." Since the Router has firewall security (NAT), the only IP address that can be seen from the Internet for your network is the Router's WAN IP address. However, even this WAN IP address for the Router can be blocked, so that the Router and network seem invisible to the Internet--see the Blocking WAN Requests description under IP Filtering in "Chapter 9: The Cable/DSL Router's Web-based Utility."

In this instance, the Router connects your Local Area Network (LAN), or the group of PCs in your home or office, to the Wide Area Network (WAN), that is, the Internet. The Router processes and regulates the data that travels between these two networks. Think of the Router as a network device with two sides: the first side is made up of your private Local Area Network (LAN) of PCs. The other, public side is the Internet, or the Wide Area Network (WAN), outside of your home or office. 4 5 Instant BroadbandTM Series If you use the Router to share your cable or DSL 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 Router. You can get the information ...
