9-16
Remote Node 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 three
routes the ZyWALL uses (see also Remote Node Setup and Backup
Remote Node Setup).) The smaller the number, the higher priority the
route has.
15
(default)
Check WAN
IP Address
Configuration of this field is optional. If you do not enter an IP address
here, the ZyWALL will use the default gateway IP address.
Configure this field to test your ZyWALL’s WAN accessibility. Enter the IP
address of a reliable nearby computer (for example, your ISP’s DNS
server address).
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.
5
Period (sec) Enter the number of seconds for the ZyWALL to wait between checks to
see if it can connect to the WAN IP address (Check WAN IP Address
field) or the default gateway. Allow more time if your destination IP
address handles lots of traffic.
3
Timeout (sec) Enter the number of seconds for your ZyWALL to wait for a ping response
from the IP Address in the Check WAN IP Address field before it times
out.
The WAN connection is considered “down” after the ZyWALL times out
the number of times specified in the Fail Tolerance field.
Use a higher the value in this field if your network is busy or congested.
