Figure 30   WAN Backup

The following table describes the fields in this screen.

Table 17   WAN Backup 

Backup Type 

Select the method that the Prestige uses to check the DSL connection. 
Select DSL Link to have the Prestige check if the connection to the DSLAM is up. 

Select ICMP to have the Prestige periodically ping the IP addresses configured in 

the Check WAN IP Address fields.

Check WAN IP 

Address1-3

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). 

Note: If you activate traffic redirect, you must configure at least one 

IP address here. 

When using a WAN backup connection, the Prestige 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 Prestige 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).

Recovery Interval  When the Prestige is using a lower priority connection (usually a WAN backup 

connection), it periodically checks to whether or not it can use a higher priority 

connection.
Type the number of seconds (30 recommended) for the Prestige to wait between 

checks. Allow more time if your destination IP address handles lots of traffic.
