Chapter 6 WAN Setup
DESCRIPTION
Type the number of seconds (3 recommended) for your ZyXEL Device to wait for a
ping response from one of the IP addresses in the Check WAN IP Address field
before timing out the request. The WAN connection is considered "down" after the
ZyXEL Device 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.
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 at least one
Check WAN IP Address.
This field sets this route's priority among the routes the ZyXEL Device uses.
The metric represents the "cost of transmission". A router determines the best route
for transmission by choosing a path with the lowest "cost". RIP routing uses hop
count as the measurement of cost, with a minimum of "1" for directly connected
networks. The number must be between "1" and "15"; a number greater than "15"
means the link is down. The smaller the number, the lower the "cost".
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.
