Recovery Interval When the device 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 device 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 device 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 device 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 Active Select this check box to have the device 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.
Metric This field sets this route's priority among the routes the device 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 IP Type the IP address of your backup gateway in dotted decimal notation. The
device automatically forwards traffic to this IP address if the device's Internet
connection terminates.
Dial Backup
Dial Active Select this check box to turn on dial backup.
If you activate dial backup, you must configure at least one Check WAN IP
Address.
Priority This field sets this route's priority among the three routes the device uses
(normal, traffic redirect and dial backup). Type a number (1 to 15) to set the
priority of the dial backup route for data transmission. The smaller the
number, the higher the priority.
If the three routes have the same metrics, the priority of the routes is as
follows:
WAN , Traffic Redirect , Dial Backup .
Port Speed Use the drop-down list box to select the speed of the connection between
the dial backup port and the external device. Available speeds are:
9600 ,
19200 , 38400 , 57600 , 115200 or 230400 bps.
User Name Type the login name assigned by your ISP.
Password Type the password assigned by your ISP.
Pri Phone Type the first (primary) phone number from the ISP for this remote node.
Some areas require dialing the pound sign # before the phone number for
local calls. Include a # symbol at the beginning of the phone numbers as
required.
