WAN Backup Setup
LABEL
DESCRIPTION
WAN Backup
Setup
Backup Type
Select the method that the P-660HWP-D1 uses to check the DSL connection.
Select
DSL Link
to have the P-660HWP-D1 check if the connection to the DSLAM
is up. Select
ICMP
to have the P-660HWP-D1 periodically ping the IP addresses
configured in the
Check WAN IP Address
fields.
Check WAN IP
Address1-3
Configure this field to test your P-660HWP-D1's WAN accessibility. Type the IP
address of a reliable nearby computer (for example, your ISP's DNS server
address).
Note: 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 P-660HWP-D1 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 P-660HWP-D1 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 P-660HWP-D1 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 P-660HWP-D1 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 P-660HWP-D1 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
P-660HWP-D1 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
Traffic redirect forwards traffic to a backup gateway when the P-660HWP-D1
cannot connect to the Internet.
Active Traffic
Redirect
Select this check box to have the P-660HWP-D1 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.
Metric
This field sets this route's priority among the routes the P-660HWP-D1 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".
Backup Gateway
Type the IP address of your backup gateway in dotted decimal notation. The P-
660HWP-D1 automatically forwards traffic to this IP address if the P-660HWP-D1's
Internet connection terminates.
