Reference Manual for the Model RP614 Web Safe Router
Advanced Configuration of the Router 7-11
6. Typethe IP Subnet Mask for this destination.
If the destinationis a single host, type 255.255.255.255.
7. Typethe Gateway IP Address, which must be a router on the same LAN segmentas the router.
8. Typea number between 1 and 15 as the Metric value.
This representsthe number of routers between your network and the destination. Usually,a
settingof 2 or 3 works, but if this is a direct connection, set it to 1.
9. Click Applyto have the static route entered into the table.
Static Route Example
As an exampleof when a static route is needed, consider the following case:
• Yourprimary Internet access is through a cable modem to an ISP.
• Youhave an ISDN router on your home network for connecting to the company where
you are employed. Thisrouter ’saddress on your LAN is 192.168.0.100.
• Yourcompany’s network is 134.177.0.0.
Whenyou first configured your router, two implicit static routes were created. A default route was
createdwith your ISP as the gateway, and a second static route was createdto your local network
for all192.168.0.x addresses. With this configuration, if you attempt to accessa device onthe
134.177.0.0 network,your router will forward your request to the ISP.The ISP forwards your
requestto the company where you are employed, and the request will likely be denied by the
company’s firewall.
In thiscase you must define a static route, telling your router that 134.177.0.0 shouldbe accessed
throughthe ISDN router at 192.168.0.100. The static route would look like Figure 7-5.
In this example:
• The DestinationIP Address and IP Subnet Mask fields specify that this static route applies to
all 134.177.x.xaddresses.
• The GatewayI P Addressfields specifies that all traffic for these addresses should be
forwarded tothe ISDN router at 192.168.0.100.
• A Metric value of 1 will work since the ISDN router is on the LAN.
• Privateis selected only as a precautionary security measure in case RIP is activated.
