DESCRIPTION
Type the number of seconds (3 recommended) for your Prestige 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 Prestige
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.
Traffic redirect forwards traffic to a backup gateway when the Prestige cannot
connect to the Internet.
Select this check box to have the Prestige 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 Prestige 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
Prestige automatically forwards traffic to this IP address if the Prestige's Internet
connection terminates.
