DESCRIPTION
Select the device HA role that the ZyWALL plays in the virtual router.
Choices are:
Master - This ZyWALL is the master ZyWALL in the virtual router. This
ZyWALL uses the virtual IP address for each monitored interface.
Note: Do not set this field to Master for two or more ZyWALLs in the
same virtual router (same cluster ID).
Backup - This ZyWALL is a backup ZyWALL in the virtual router. This
ZyWALL does not use any of the virtual IP addresses.
This field is available for a backup ZyWALL. Type the priority of the
backup ZyWALL. The backup ZyWALL with the highest value takes over
the role of the master ZyWALL if the master ZyWALL becomes
unavailable. The priority must be between 1 and 254. (The master
interface has priority 255.)
This field is available for a backup ZyWALL. Select this if this ZyWALL
should become the master ZyWALL if a lower-priority ZyWALL is the
master when this one is enabled. (If the role is master, the ZyWALL
preempts by default.)
Click Advanced to display more settings. Click Basic to display fewer
settings.
Type the cluster ID number. A virtual router consists of a master
ZyWALL and all of its backup ZyWALLs. If you have multiple ZyWALL
virtual routers on your network, use a different cluster ID for each
virtual router.
Select the authentication method the virtual router uses. Every interface
in a virtual router must use the same authentication method and
password. Choices are:
None - this virtual router does not use any authentication method.
Text - this virtual router uses a plain text password for authentication.
Type the password in the field next to the radio button. The password
can consist of alphanumeric characters, the underscore, and some
punctuation marks (+-/*= :; .! @$&%#~ ' \ () ), and it can be up to
eight characters long.
IP AH (MD5) - this virtual router uses an encrypted MD5 password for
authentication. Type the password in the field next to the radio button.
The password can consist of alphanumeric characters, the underscore,
and some punctuation marks (+-/*= :; .! @$&%#~ ' \ () ), and it can
be up to eight characters long.
See Authentication Types on page 259

This field identifies the interface. At the time of writing, only the
