Remote Node Setup 10-13
Table 10-6 Traffic Redirect Setup
FIELD DESCRIPTION EXAMPLE
Configuration:
Backup
Gateway IP
Address
Enter the IP address of your backup gateway in dotted decimal notation.
The ZyWALL automatically forwards traffic to this IP address if the
ZyWALL’s Internet connection terminates.
0.0.0.0
Metric Enter a number from 1 to 15 to set this route’s priority among the
ZyWALL’s routes. The smaller the number, the higher priority the route
has.
15
(default)
Check WAN
IP Address
Enter the IP address of a reliable nearby computer (for example, your
ISP’s DNS server address) to test your ZyWALL’s WAN accessibility.
The ZyWALL uses the default gateway IP address if you do not enter an
IP address here.
If you are using PPTP or PPPoE Encapsulation, enter “0.0.0.0” to
configure the ZyWALL to check the PVC (Permanent Virtual Circuit) or
PPTP tunnel.
0.0.0.0
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.
2
Period (sec) Enter the time interval (in seconds) between WAN connection checks.
Five to 60 is usually a good number.
5
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.
