The following table describes the labels in this screen.
Table 38 Network > WAN > Traffic Redirect
LABEL DESCRIPTION
Traffic Redirect
Active
Select this check box to have the ZyXEL Device use traffic redirect if the normal
WAN connection goes down.
Note: If you activate traffic redirect, you must configure the Check
WAN IP Address field.
Backup Gateway
IP Address
Type the IP address of your backup gateway in dotted decimal notation. The
ZyXEL Device automatically forwards traffic to this IP address if the ZyXEL
Device's Internet connection terminates.
Check WAN IP
Address
Configure this field to test your ZyXEL Device's WAN accessibility. Type the IP
address of a reliable nearby computer (for example, your ISP's DNS server
address).
Note: If you activate either traffic redirect or dial backup, you must
configure an IP address here.
When using a WAN backup connection, the ZyXEL Device periodically pings the
addresses configured here and uses the other WAN backup connection (if
configured) if there is no response.
Fail Tolerance Type the number of times (2 recommended) that your ZyXEL Device may ping the
IP addresses configured in the Check WAN IP Address field without getting a
response before switching to a WAN backup connection (or a different WAN
backup connection).
Period (sec) The ZyXEL Device 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.
Timeout (sec) Type the number of seconds (1 to 10) for your ZyXEL Device 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.
Apply Click this button to save your settings.
Reset Click this button to return all the fields in this screen to their default values.
