Metric

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".

Check WAN IP 

Address

Configuration of this field is optional. If you do not enter an IP address here, the 

Prestige will use the default gateway IP address. Configure this field to test your 

Prestige'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 Prestige to check the PVC (Permanent 

Virtual Circuit) or PPTP tunnel.

Fail Tolerance

Type the number of times your Prestige may attempt and fail to connect to the Internet 

before traffic is forwarded to the backup gateway.

Period 

(seconds)

Type the number of seconds for the Prestige 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 

(seconds)

Type the number of seconds for your Prestige 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 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.
