Prestige 660R ADSL 2+ Access Gateway
6-10 WAN Setup
Table 6-2 WAN Backup
LABEL DESCRIPTION
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).
If you activate either traffic redirect or dial backup, 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 fields 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.
Timeout 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 fields
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
Active Select this check box to have the Prestige use traffic redirect if the normal WAN
connection goes down.
If you activate traffic redirect, you must configure at least
one Check WAN IP Address .
