Prestige 662HW Series User’s Guide
Chapter 9 WAN Setup 120
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 field 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.
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 Prestige 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
Prestige automatically forwards traffic to this IP address if the Prestige's Internet
connection terminates.
Dial Backup
Active Select this check box to turn on dial backup.
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 three routes the Prestige 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.
