Table 26-6 Menu 11.6: Traffic Redirect Setup

FIELD

DESCRIPTION

EXAMPLE

 

 

 

Active

Press [SPACE BAR] and select Yes (to enable) or No (to disable) traffic

Yes

 

redirect setup. The default is No.

 

 

When the Active field is Yes, you must configure every field in this screen

 

 

unless you are using PPPoE or PPTP encapsulation (except Check WAN

 

 

IP Address and Timeout).

 

 

If you don’t configure these fields and are using PPTP or PPPoE

 

 

encapsulation, then the ZyWALL checks the PPPoE channel or PPTP

 

 

tunnel to determine if the WAN connection is down.

 

 

 

 

Configuration:

 

 

 

 

 

Backup Gateway

Enter the IP address of your backup gateway in dotted decimal notation.

0.0.0.0

IP Address

The ZyWALL automatically forwards traffic to this IP address if the

 

 

 

 

ZyWALL’s Internet connection terminates.

 

 

 

 

Metric

Enter a number from 1 to 15 to set this route’s priority among the

15

 

ZyWALL’s routes (see the Metric section in the WAN and Dial Backup

(default)

 

Setup chapter) The smaller the number, the higher priority the route has.

 

Check WAN IP

Enter the IP address of a reliable nearby computer (for example, your

0.0.0.0

Address

ISP’s DNS server address) to test your ZyWALL’s WAN accessibility.

 

 

The ZyWALL uses the default gateway IP address if you do not enter an

 

 

IP address here.

 

 

If you are using PPTP or PPPoE Encapsulation, enter “0.0.0.0” to

 

 

configure the ZyWALL to check the PVC (Permanent Virtual Circuit) or

 

 

PPTP tunnel.

 

 

 

 

Fail Tolerance

Enter the number of times your ZyWALL may attempt and fail to connect

2

 

to the Internet before traffic is forwarded to the backup gateway. Two to

 

 

five is usually a good number.

 

 

 

 

Period (sec)

Enter the time interval (in seconds) between WAN connection checks.

5

 

Five to 60 is usually a good number.

 

 

 

 

Timeout (sec)

Enter the number of seconds the ZyWALL waits for a ping response from

 

 

the IP Address in the Check WAN IP Address field before it times out.

 

 

The number in this field should be less than the number in the Period

3

 

field. Three to 50 is usually a good number.

 

 

The WAN connection is considered “down” after the ZyWALL times out

 

 

the number of times specified in the Fail Tolerance field.
