Table 126   Menu 11.1.5: Traffic Redirect Setup

Active

Select this to set up a backup gateway in case the default gateway is not 

available. (For example, this might happen if the Internet connection goes 

down.) Clear this if you do not have a backup gateway.

Configuration

Backup Gateway IP 

Address

Enter the IP address of the backup gateway. The ZyXEL Device automatically 

uses this gateway if the default gateway is not available anymore.

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". A backup gateway usually has a higher cost than the default 

gateway so that the ZyXEL Device uses the default gateway as long as it is 

available.

Check WAN IP 

Address

Enter the IP address of a reliable nearby computer the ZyXEL Device uses to 

test whether or not the default gateway is available anymore. For example, use 

one of your ISP’s DNS server addresses.
If you enter 0.0.0.0, the test fails every time.

Fail Tolerance

Enter the number of consecutive times the ZyXEL Device may attempt and fail 

to find the reliable nearby computer at Check WAN IP Address before it starts 

using the backup gateway. 2-5 are typical choices.

Period(sec)

Enter the number of seconds between attempts to find the reliable nearby 

computer at Check WAN IP Address. 5-60 are typical choices.

Timeout(sec)

Enter the number of seconds the ZyXEL Device waits for a response from the 

reliable nearby computer at Check WAN IP Address before the attempt is a 

failure. 3-50 are typical choices, but this number should be less than the 

Period.
