Click this button to display a greater or lesser number of configuration 
fields.

Enable VRRP 
Group

Select this to make the specified interface part of the virtual router. Clear 
this to take the specified interface out of the virtual router. Enabling a 
VRRP group has the ZyWALL monitor the connection of the group’s 
interface.

Name

This field is read-only if you are editing the VRRP group. Type the name 
of the VRRP group. This field must be unique in the ZyWALL, but it is not 
used in the virtual router. The virtual router uses the VRID. The name 
can consist of alphanumeric characters, the underscore, and the dash 
and may be up to fifteen characters long.

Description

Type the description of the VRRP group. This field is only for your 
reference. It may be up to sixty printable ASCII characters long.

Interface 
Name

Select the interface in this device that is part of the virtual router. You 
can only select interfaces that have static IP addresses. Connect the 
interface to the same subnet as the group’s interface on the other 
ZyWALL. 

Manage IP

Enter the interface’s IP address for management access. You can use 
this IP address to access the ZyWALL whether it is the master or a 
backup. This management IP address should be in the same subnet as 
the interface IP address so the backup ZyWALL cannot synchronize with 
the master via this VRRP interface.

Manage IP 
Subnet Mask

Enter the subnet mask of the interface’s management IP address.

Role

Select the role that you want the interface to play in the virtual router. 
Choices are:

Master - This interface is the master interface in the virtual router. The 
interface always uses its virtual IP address when its status is active.

Note: Do not set this field to Master for two or more ZyWALLs in the 

same virtual router (same VR ID).

Backup - This interface is a backup interface in the virtual router. The 
current role depends on the other ZyWALLs in the virtual router.

Priority

This field is available if the selected interface is a Backup interface. Type 
the priority of the backup interface. The backup interface with the 
highest value takes over the role of the master interface if the master 
interface becomes unavailable. The priority must be between 1 and 254. 
(The master interface has priority 255.)

Preempt

This field is available if the selected interface is a Backup interface. 
Select this if the selected interface should become the master interface if 
a lower-priority interface is the master when this one is enabled. (If the 
role is Master, the interface preempts by default.)
