Routing
10.1 Policy and Static Routes Overview
Use policy routes and static routes to override the USG’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 USG’s LAN interface. The USG
routes most traffic from
A
to the Internet through the USG’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.

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.
