5.9 WAN Backup Advanced Screen
To change your ZyXEL Device’s WAN backup advanced settings, click WAN > WAN
Backup Setup > Advanced Setup . The screen appears as shown.
Timeout Type the number of seconds (3 recommended) for your ZyXEL 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
ZyXEL 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 redirect forwards traffic to a backup gateway when the ZyXEL Device cannot
connect to the Internet.
Active Traffic
Redirect
Select this check box to have the ZyXEL Device 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 ZyXEL 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 Type the IP address of your backup gateway in dotted decimal notation. The ZyXEL
Device automatically forwards traffic to this IP address if the ZyXEL Device's
Internet connection terminates.
Dial Backup
Active Dial
Backup
Select this box to activate dial up backup.
Metric This field sets this route's priority among the three routes the ZyXEL 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 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.
