Use policy routes and static routes to override the ZyWALL's default routing

behavior in order to send packets through the appropriate the interface or VPN

For example, the next figure shows a computer (A) connected to the ZyWALL's

LAN interface. The ZyWALL routes most traffic from A to the Internet through the

ZyWALL's default gateway (R1). You create one policy route to connect to

services offered by your ISP behind router R2. You create another policy route to

communicate with a separate network behind another router (R3) connected to

Figure 172 Example of Policy Routing Topology

You also use policy routes to send traffic through VPN tunnels. Using the VPN

wizard automatically configures a corresponding policy route, but you must

manually configure a policy route if you use the main VPN screens to configure a

VPN connection.

Note: You can generally just use policy routes. You only need to use static routes if

you have a large network with multiple routers where you use RIP or OSPF to

propagate routing information to other routers.
