Enable VRRP	Select this to make the specified interface part of the virtual router. Clear
Group	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	Select the interface in this device that is part of the virtual router. You
Name	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	Enter the subnet mask of the interface’s management IP address.
Subnet Mask
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.)
