25.1.1Before You Begin
•Configure a static IP address for each interface that you will have device HA monitor.

25.3 Active-Passive Mode Device HA
Virtual Router
The master and backup ZyWALL form a single ‘virtual router’.
Cluster ID
You can have multiple ZyWALL virtual routers on your network. Use a different cluster ID to identify each virtual router.
Monitored Interfaces in Active-Passive Mode Device HA
You can select which interfaces device HA monitors. If a monitored interface on the ZyWALL loses its connection, device HA has the backup ZyWALL take over.
Enable monitoring for the same interfaces on the master and backup ZyWALLs. Each monitored interface must have a static IP address and be connected to the same subnet as the corresponding interface on the backup or master ZyWALL.
