Synchronize Screen - ZyXEL Communications ZyWALL 1050 User Manual

ZyWALL 1050 User's Guide
Backup ZyWALLs cannot get updates for services to which they have not subscribed. For
example, if a backup ZyWALL has not subscribed to IDP, it does not get IDP updates from the
master ZyWALL.
Synchronization affects the entire device configuration. You can only configure one set of
settings for synchronization, regardless of how many VRRP groups you might configure. The
ZyWALL uses Secure FTP (on a port number you can change) to synchronize, but it is still
recommended that the backup ZyWALL synchronize with a master ZyWALL on a secure
network.
Synchronization can be either done manually or scheduled regularly, and it is initiated by the
backup ZyWALL. The following restrictions apply.
• The backup ZyWALL must have at least one active VRRP group.
• The backup ZyWALL cannot be the master in any active VRRP group. This refers to the
actual role at the time of synchronization, not the Role setting in the VRRP group.

Use this screen if you want the ZyWALL to get or to send updated IDP signatures, and
configuration information in the virtual router.
Note: You can only set up synchronization with other ZyWALL 1050s running the
same firmware version.
Note: The backup router reboots during synchronization.
