Table 37   Menu 2 WAN Backup Setup

Check Mechanism

Press [SPACE BAR] and then press [ENTER] to select the method that the 

Prestige uses to check the DSL connection.
Select DSL Link to have the Prestige check the DSL connection’s physical 

layer. 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). 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.

KeepAlive 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(sec) 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.

ICMP Timeout

Type the number of seconds for an ICMP session to wait for the ICMP 

response.

Traffic Redirect

Press [SPACE BAR] to select Yes or No. 
Select Yes and press [ENTER] to configure Menu 2.1 Traffic Redirect Setup.
Select No (default) if you do not want to configure this feature. 

When you have completed this menu, press [ENTER] at the prompt “

Press ENTER to Confirm 

or ESC to Cancel:

”  to save your configuration, or press [ESC] at any time to cancel.
