ZyXEL Communications 1000 User Manual

ZyWALL USG 1000 User’s Guide

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 272   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. 

• Use  the Policy Route screens (see 

) to list and 

configure policy routes.
