Chapter 5 WAN Setup
Recovery Interval When the ZyXEL Device is using a lower priority connection (usually a WAN backup
connection), it periodically checks to whether or not it can use a higher priority
connection.
Type the number of seconds (30 recommended) for the ZyXEL Device to wait
between checks. Allow more time if your destination IP address handles lots of
traffic.
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 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".
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.
Advanced Setup
Click this to configure advanced settings for the dial-backup connection.
