Policy and Static Routes
12.1 Policy and Static Routes Overview
Use policy routes and static routes to override the UAG’s default routing behavior in order to send
packets through the appropriate interface.
For example, the next figure shows a computer (
A
) connected to the UAG’s LAN interface. The UAG
routes most traffic from
A
to the Internet through the UAG’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.

12.1.2 What You Need to Know
Policy Routing
Traditionally, routing is based on the destination address only and the UAG takes the shortest path
to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing
behavior and alter the packet forwarding based on the policy defined by the network administrator.
