ProSafe VPN Firewall 200 FVX538 Reference Manual

Static Route Example

For example, you may require a static route if:
• Your primary Internet access is through a cable modem to an ISP.
• You have an ISDN firewall on your home network for connecting to the company where you
are employed. This firewall's address on your LAN is 192.168.1.100.
• Your company's network is 134.177.0.0.
When you first configured your VPN firewall, two implicit static routes were created. A default
route was created with your ISP as the gateway, and a second static route was created to your local
network for all 192.168.1.x addresses. With this configuration, if you attempt to access a device on
the 134.177.0.0 network, your VPN firewall will forward your request to the ISP. The ISP
forwards your request to the company where you are employed, and the request will likely be
denied by the company's firewall.
In this case you must define a static route, telling your VPN firewall that 134.177.0.0 should be
accessed through the ISDN firewall at 192.168.1.100.
In this example:
• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to
all 134.177.x.x addresses.
• The Gateway IP Address fields specifies that all traffic for these addresses should be
forwarded to the ISDN firewall at 192.168.1.100.
• A Metric value of 1 will work since the ISDN firewall is on the LAN.
• Private is selected only as a precautionary security measure in case RIP is activated.

Configuring Routing Information Protocol (RIP)

RIP (Routing Information Protocol, RFC 2453) is an Interior Gateway Protocol (IGP) that is
commonly used in internal networks (LANs). It allows a router to exchange its routing information
automatically with other routers, and allows it to dynamically adjust its routing tables and adapt to
changes in the network. RIP is disabled by default.
To configure RIP:
1. Select Network Configuration from the main menu and Routing from the submenu. The
Routing screen will display (see
3-16
Figure 3-6 on page 3-14).
