can be included in the active-passive mode virtual router. The member interfaces of any
bridge interfaces do not display separately.
Virtual Router IP /
Netmask
This is the master ZyWALL’s (static) IP address and subnet mask for this interface. If a
backup takes over for the master, it uses this IP address. These fields are blank if the
interface is a DHCP client or has no IP settings.
Management IP /
Netmask
This field displays the interface’s management IP address and subnet mask. You can use
this IP address and subnet mask to access the ZyWALL whether it is in master or backup
mode.
Link Status This tells whether the monitored interface’s connection is down or up.
Synchronization Use synchronization to have a backup ZyWALL copy the master ZyWALL’s configuration,
certificates.
Every interface’s management IP address must be in the same subnet as the interface’s
IP address (the virtual router IP address).
Server Address If this ZyWALL is set to backup role, enter the IP address or Fully-Qualified Domain
Name (FQDN) of the ZyWALL from which to get updated configuration. Usually, you
should enter the IP address or FQDN of a virtual router on a secure network.
If this ZyWALL is set to master role, this field displays the ZyWALL’s IP addresses and/or
Fully-Qualified Domain Names (FQDN) through which ZyWALLs in backup role can get
updated configuration from this ZyWALL.
Sync. Now This displays if the ZyWALL is set to use active-passive mode device HA, the ZyWALL is in
the backup role and device HA is enabled. Click this to copy the specified ZyWALL’s
configuration.
Server Port If this ZyWALL is set to the backup role, enter the port number to use for Secure FTP
when synchronizing with the specified master ZyWALL.
If this ZyWALL is set to master role, this field displays the ZyWALL’s Secure FTP port
number. Click the Configure link if you need to change the FTP port number.
Every ZyWALL in the virtual router must use the same port number. If the master
ZyWALL changes, you have to manually change this port number in the backups.
Password Enter the password used for verification during synchronization. Every ZyWALL in the
virtual router must use the same password.
If you leave this field blank in the master ZyWALL, no backup ZyWALLs can synchronize
from it.
If you leave this field blank in a backup ZyWALL, it cannot synchronize from the master
ZyWALL.
Retype to Confirm Type the password again here to confirm it.
Auto Synchronize Select this to get the updated configuration automatically from the specified ZyWALL
according to the specified Interval. The first synchronization begins after the specified
Interval; the ZyWALL does not synchronize immediately.
Interval When you select Auto Synchronize, set how often the ZyWALL synchronizes with the
master.
Next Sync Time This appears the next time and date (in hh:mm yyyy-mm-dd format) the ZyWALL will
synchronize with the master.
