This section introduces the auxiliary interface and then explains the screen for it.

Use the auxiliary interface to dial out from the ZyWALL’s auxiliary port. For example, you 
might use this interface as a backup WAN interface.

You have to connect an external modem to the ZyWALL’s auxiliary port to use the auxiliary

2 The load auxiliary interface must connect to satisfy load-balancing requirements. You

issues the command

Ping Check

The interface can regularly ping the gateway you specified to make sure it is still 
available. You specify how often the interface pings the gateway, how long to 
wait for a response before the attempt is a failure, and how many consecutive 
failures are required before the ZyWALL stops routing to the gateway. The 
ZyWALL resumes routing to the gateway the first time the gateway 
acknowledges the ping.
