ISG50 User’s Guide 289
CHAPTER 14
Policy and Static Routes
14.1 Policy and Static Routes Overview
Use policy routes and static routes to override the ISG50’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 ISG50’s LAN interface. The
ISG50 routes most traffic from A to the Internet through the ISG50’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 194 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.
