ZyWALL USG 2000 Support Notes
F11. How do I use the traffic redirect feature in ZyWALL USG 2000?
If you have a router located in LAN, you could regard the router as a gateway and fill its
address in a gateway field of the LAN interface which connects to the LAN router. Then,
configure the interface as a passive member of the trunk which you use in the policy routing.
In case all main links in the trunk go down, passive link (i.e. the LAN router) would be
activated to maintain the connectivity.
Note: While you configure the gateway address in the interface, please also choose a suitable
metric for the gateway or it would interfere with main links.
F12. Why can't ZyWALL learn the route from RIP and/or OSPF?
ZyWALL blocks RIP/OSPF routing advertisement from WAN/DMZ by default. If you find
that it fails to learn the routes, check your firewall to-ZyWALL rules.
