ZyWALL 2 Plus User's Guide
DESCRIPTION
Select this check box to have the ZyWALL use traffic redirect if the normal WAN
connection goes down.
Type 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.
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. Type the IP address of a reliable nearby computer (for
example, your ISP's DNS server address).
Type how many WAN connection checks can fail (1 to 10) before the connection is
considered "down" (not connected). The ZyWALL still checks a "down" connection to
detect if it reconnects.
The ZyWALL tests a WAN connection by periodically sending a ping to either the
default gateway or the address in the Check WAN IP Address field.
Type a number of seconds (5 to 300) to set the time interval between checks. Allow
more time if your destination IP address handles lots of traffic.
Type the number of seconds (1 to 10) for your ZyWALL to wait for a response to the
ping before considering the check to have failed. This setting must be less than the
Period. Use a higher value in this field if your network is busy or congested.
Click Apply to save your changes back to the ZyWALL.
Click Reset to begin configuring this screen afresh.
