work, check whether the firewall rule from WAN to LAN is disabled.

F10. Why port trigger does not work?

The port trigger will work only when there is a connection matching that policy route

rule. Please note that firewall may block those triggered services. So, if you have

problems with triggering the service, check firewall settings and its logs too.

F11. How do I use the traffic redirect feature in ZyWALL USG?

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.
