BEFSR41 User Guide Apr 2000.qxd 4/27/00 3:20 PM Page 9 EtherFast Cable/DSL Routers Connecting the Cable/DSL Router to Your Network Overview Unlike a simple hub or switch, the setup of the Cable/DSL Router consists of more than simply plugging everything together. Because the Router acts as a DHCP server, you will have to set some values within the Router, and also configure your networked PCs to accept the IP Addresses the Router chooses to assign them.
BEFSR41 User Guide Apr 2000.qxd 4/27/00 3:20 PM Page 10 Instant Broadband Series DHCP (Dynamic Host Configuration Protocol) DHCP is software that automatically assigns IP addresses to client stations logging onto a TCP/IP network. DHCP eliminates having to manually assign permanent IP addresses to every device on your network. DHCP software typically runs in servers and is also found in network devices such as Routers.
BEFSR41 User Guide Apr 2000.qxd 4/27/00 3:20 PM Page 11 EtherFast Cable/DSL Routers 4. Connect the power-supply cable to the Power port on the rear of the Router, then plug the supplied AC power cable into a power outlet.

BEFSR41 User Guide Apr 2000.qxd 4/27/00 3:21 PM Page 25 EtherFast Cable/DSL Routers Forwarding Port forwarding sets up public services on your network. When users from the Internet make certain requests of your network, the router will forward those requests to the appropriate computer. The router's DHCP function must be disabled to use Forwarding. Forwarding is generally used to set up a webserver, ftp server, or e-mail server on your network. To add a server using Forwarding: 1.
BEFSR41 User Guide Apr 2000.qxd 4/27/00 3:21 PM Page 26 Instant Broadband Series Dynamic Routing With Dynamic Routing you can automatically adjust to physical changes in the network's layout. The router, using the RIP protocol, determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network. To set up Dynamic Routing: 1. Choose the correct working mode.
BEFSR41 User Guide Apr 2000.qxd 4/27/00 3:21 PM Page 27 EtherFast Cable/DSL Routers Static Routing If your Router is connected to more than one network, it may be necessary to set up a static route between them. A static route is a pre-determined pathway that network information must travel to reach a specific host or network. Click the Show Routing Table button to view the current static routing configuration. To create a static route entry: 1. Select Static Route Entry from the drop down list.
BEFSR41 User Guide Apr 2000.qxd 4/27/00 3:21 PM Page 28 Instant Broadband Series 2. Enter the following data to create a new static route: Destination LAN IP The Destination LAN IP is the Address of the remote network or host to which you want to assign a static route.
