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 to have the ZyXEL Device use a dial-backup connection if the normal 

WAN connection goes down.

Note: If you activate dial backup, 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

than "15" means the link is down. The smaller the number, the lower the "cost".

Port Speed

Use the drop-down list box to select the speed of the connection between the DSL 

port and the external device.

User Name

Type the login name assigned by your ISP.

Password

Type the password assigned by your ISP.

Primary Phone 

Number

Type the first (primary) phone number from the ISP for this remote node. If the 

Primary Phone number is busy or does not answer, your ZyWALL dials the 

Secondary Phone number, if available. (See Advanced Setup.) 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.
