DESCRIPTION
Select this to have device HA monitor the status of this interface's
connection.
This identifies the interface.
Note: Do not connect the bridge interfaces on two ZyWALLs without
device HA activated on both. Doing so could cause a
broadcast storm.
Either activate device HA before connecting the bridge interfaces or
disable the bridge interfaces, connect the bridge interfaces, activate
device HA, and finally reactivate the bridge interfaces.
This is the interface's (static) IP address and subnet mask in the virtual
router. Whichever ZyWALL is currently serving as the master uses this
virtual router IP address and subnet mask. These fields are blank if the
interface is a DHCP client or has no IP settings.
Enter the interface's IP address for management access. You can use
this IP address to access the ZyWALL whether it is the master or a
backup. This management IP address should be in the same subnet as
the interface IP address.
Enter the subnet mask of the interface's management IP address.
Click OK to save your changes back to the ZyWALL.
