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.

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.

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.
