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.

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.

9.1.1What You Can Do in this Chapter

Use the Policy Route screens (see Section 9.2 on page 189) to list and configure policy routes.

Use the Static Route screens (see Section 9.3 on page 195) to list and configure static routes.
