CHAPTER 15

Policy and Static Routes

15.1 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 297 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.

15.1.1 What You Can Do in this Chapter
