ZyWALL's Internet connection terminates.
Metric Enter a number from 1 to 15 to set this route's priority among the

Check WAN Enter the IP address of a reliable nearby computer (for example, your

The ZyWALL uses the default gateway IP address if you do not enter an
IP address here.

configure the ZyWALL to check the PVC (Permanent Virtual Circuit) or
PPTP tunnel.
Fail Tolerance Enter the number of times your ZyWALL may attempt and fail to connect
to the Internet before traffic is forwarded to the backup gateway. Two to
five is usually a good number.
Period (sec) Enter the time interval (in seconds) between WAN connection checks.
Five to 60 is usually a good number.
Timeout (sec) Enter the number of seconds the ZyWALL waits for a ping response from
the IP Address in the Check WAN IP Address field before it times out.
The number in this field should be less than the number in the Period
field. Three to 50 is usually a good number.
The WAN connection is considered "down" after the ZyWALL times out
the number of times specified in the Fail Tolerance field.
