Device HA
Use device HA to increase network reliability. Device HA lets a backup ZyWALL / USG (B)
automatically take over if a master ZyWALL / USG (A) fails.
Figure 24 Device HA Backup Taking Over for the Master
39.1 Device HA Overview
Active-Passive Mode
Active-passive mode lets a backup ZyWALL / USG take over if the master ZyWALL / USG fails.
The ZyWALL / USGs must all support and be set to use the same device HA mode (either active-
passive or legacy).
Management Access
You can configure a separate management IP address for each interface. You can use it to access
the ZyWALL / USG for management whether the ZyWALL / USG is the master or a backup. The
management IP address should be in the same subnet as the interface IP address.
Synchronization
Use synchronization to have a backup ZyWALL / USG copy the master ZyWALL / USG’s
configuration, signatures (anti-virus, IDP/application patrol, and system protect), and certificates.
Note: Only ZyWALL / USGs of the same model and firmware version can synchronize.
Otherwise you must manually configure the master ZyWALL / USG’s settings on the backup (by
editing copies of the configuration files in a text editor for example).
