DESCRIPTION

 

 

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

Select this check box to have the ZyXEL Device use traffic redirect if the normal

Redirect

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

Select this box to activate dial up backup.

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.
