LABEL
Check WAN
Configuration of this field is optional. If you do not enter an IP address here, the ZyWALL
IP Address
will use the default gateway IP address. Configure this field to test your ZyWALL's WAN
accessibility. Type the IP address of a reliable nearby computer (for example, your ISP's
DNS server address). If you are using PPTP or PPPoE Encapsulation, type "0.0.0.0" to
configure the ZyWALL to check the PVC (Permanent Virtual Circuit) or PPTP tunnel.
Fail Tolerance
Type the number of times your ZyWALL may attempt and fail to connect to the Internet
before traffic is forwarded to the backup gateway.
Period (sec)
Type 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 default gateway.
Allow more time if your destination IP address handles lots of traffic.
Timeout (sec)
Type 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 value in this field if your network is busy or congested.
