DESCRIPTION

 

 

Active/Passive

Select the Active/Passive (fail over) operation mode to have the ZyWALL use the

(Fail Over) Mode

second highest priority WAN port as a back up. This means that the ZyWALL will

 

normally use the highest priority (primary) WAN port (depending on the priorities

 

you configure in the Route Priority fields). The ZyWALL will switch to the

 

secondary (second highest priority) WAN port when the primary WAN port's

 

connection fails.

Fall Back to

This field determines the action the ZyWALL takes after the primary WAN port fails

Primary WAN

and the ZyWALL starts using the secondary WAN port.

When Possible

Select this check box to have the ZyWALL change back to using the primary WAN

 

port when the ZyWALL can connect through the primary WAN port again.

 

Clear this check box to have the ZyWALL continue using the secondary WAN port,

 

even after the ZyWALL can connect through the primary WAN port again. The

 

ZyWALL continues to use the secondary WAN port until it's connection fails (at

 

which time it will change back to using the primary WAN port if its connection is up.

Active/Active

Select Active/Active Mode to have the ZyWALL use both of the WAN ports at the

Mode

same time and allow you to enable load balancing.

Load Balancing

Select Least Load First, Weighted Round Robin or Spillover to activate load

Algorithm

balancing and set the related fields. Otherwise, select None.

 

Refer to Section 7.7 on page 133 for load balancing configuration.

 

 

Route Priority

 

 

 

WAN1

The default WAN connection is "1' as your broadband connection via the WAN port

WAN2

should always be your preferred method of accessing the WAN. The ZyWALL

switches from WAN port 1 to WAN port 2 if WAN port 1's connection fails and then

Traffic Redirect

back to WAN port 1 when WAN port 1's connection comes back up. The default

Dial Backup

priority of the routes is WAN 1, WAN 2, Traffic Redirect and then Dial Backup:

 

You have three choices for an auxiliary connection (WAN 2, Traffic Redirect and

 

Dial Backup) in the event that your regular WAN connection goes down. If Dial

 

Backup is preferred to Traffic Redirect, then type "14" in the Dial Backup Priority

 

(metric) field (and leave the Traffic Redirect Priority (metric) at the default of

 

"15").

 

The Dial Backup field is available only when you enable the corresponding dial

 

backup feature in the Dial Backup screen.

Connectivity

 

Check

 

Check Period

The ZyWALL tests a WAN connection by periodically sending a ping to either the

 

default gateway or the address in the Ping this Address field.

 

Type a number of seconds (5 to 300) to set the time interval between checks. Allow

 

more time if your destination IP address handles lots of traffic.

Check Timeout

Type the number of seconds (1 to 10) for your ZyWALL to wait for a response to the

 

ping before considering the check to have failed. This setting must be less than the

 

Check Period. Use a higher value in this field if your network is busy or congested.

Check Fail

Type how many WAN connection checks can fail (1-10) before the connection is

Tolerance

considered "down" (not connected). The ZyWALL still checks a "down" connection

 

to detect if it reconnects.
