interface, ZyWALL 1050 will select this as default route and traffic can’t go out from the

ZyWALL 1050.

F06. Why can’t I ping to the, Internet, after I shutdown the primary WAN

interface?

ZyWALL 1050 routes packets by checking session information first. Once packet matched a

session that is already created, it would not lookup the routing table. So the interface status

change doesn’t affect the routing result until a new session is created. If you continually ping

internet host and shutdown the ZyWALL 1050 primary WAN interface, the ping packet still

matches the original session, which is bound to primary WAN interface already. The session

timeout for ICMP is 15 second.

F07. Why don't the virtual server or port trigger work?

If virtual server or port trigger (or any traffic from WAN zone to LAN zone) doesn’t work,

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

F08. Why don't the port trigger 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.

F09. How do I use the traffic redirect feature in ZyWALL 1050?

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
