Lets say that you have the WAN operation mode set to active/passive, meaning the ZyWALL
uses the second highest priority WAN interface as a back up. The WAN 1 route has a metric of
"2", the WAN 2 route has a metric of "3", the traffic-redirect route has a metric of "14" and the
dial-backup route has a metric of "15". In this case, the WAN 1 route acts as the primary
default route. If the WAN 1 route fails to connect to the Internet, the ZyWALL tries the WAN
2 route next. If the WAN 2 route fails, the ZyWALL tries the traffic-redirect route. In the same
manner, the ZyWALL uses the dial-backup route if the traffic-redirect route also fails.

The dial-backup or traffic redirect routes cannot take priority over the WAN 1 and WAN 2
routes.

Mapping a WAN Interface to a Local Host
You can set the ZyWALL to send all of a local computer’s traffic through the same WAN
interface. This is useful when a redirect server forwards a user request for a file and informs
the file server that a particular WAN IP address is requesting the file. If the user’s subsequent
sessions came from a different WAN IP address, the file server would deny the request. Here
is an example.
