Cluster IDs for Multiple Virtual Routers
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.
Virtual Router and Management IP Addresses
• If a backup takes over for the master, it uses the master’s IP addresses. These IP addresses are
know as the virtual router IP addresses.
• Each interface can also have a management IP address. You can connect to this IP address to
manage the ZyWALL regardless of whether it is the master or the backup.
For example, ZyWALL B takes over A’s 192.168.1.1 LAN interface IP address. This is a virtual router
IP address. ZyWALL A keeps it’s LAN management IP address of 192.168.1.5 and ZyWALL B has its
own LAN management IP address of 192.168.1.6. These do not change when ZyWALL B becomes
the master.
