EtherFast Cable/DSL Router with 8-Port Switch

•Select Entry. Select the number of the static route from the drop-down menu. The Router supports up to 20 static route entries.

•Delete Entry. If you need to delete a route, select its number from the drop-down menu, and click the Delete Entry button.

•Destination IP Address. The Destination IP Address is the address of the remote network or host to which you want to assign a static route. Enter the IP address of the host for which you wish to create a static route. If you are building a route to an entire network, be sure that the network portion of the IP address is set to 0. For example, the Router’s standard IP address is 192.168.1.1. Based on this address, the address of the routed network is 192.168.1, with the last digit determining the Router’s place on the network. Therefore you would enter the IP address 192.168.1.0 if you wanted to route to the Router’s entire network, rather than just to the Router.

•Subnet Mask. The Subnet Mask (also known as the Network Mask) determines which portion of an IP address is the network portion, and which portion is the host portion. Take, for example, a network in which the Subnet Mask is 255.255.255.0. This determines (by using the values 255) that the first three numbers of a network IP address identify this particular network, while the last digit (from 1 to 254) identifies the specific host.

•Gateway. This IP address should be the IP address of the gateway device that allows for contact between the Router and the remote network or host.

•Hop Count. This determines the maximum number of steps between network nodes that data packets will travel. A node is any device on the network, such as PCs, print servers, routers, etc.

•Interface. Select LAN or Internet, depending on the location of the static route’s final destination.

•Show Routing Table. Click the Show Routing Table button to open a screen displaying how data is routed through your LAN. For each route, the Destination LAN IP address, Subnet Mask, Default Gateway, Hop Count, and Interface are displayed. Click the Refresh button to update the information. See Figure 7-14.
