CHAPTER 9
Policy and Static Routes
9.1 Policy and Static Routes Overview
Use policy routes and static routes to override the ZyWALL’s default routing behavior in order to
send packets through the appropriate interface or VPN tunnel.
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 the LAN.
Figure 107 Example of Policy Routing Topology
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.
