In this field…
Do this…
Group ID If multiple HA clusters exist on the same network segment, type the ID
number of the cluster to which the gateway should belong.
This must be an integer between 1 and 255.
The default value is 55. If only one HA cluster exists, there is no need
to change this value.
Sample Implementation on Two Gateways
The following procedure illustrates how to configure HA for the following two
Safe@Office gateways, Gateway A and Gateway B:

The gateways have two internal networks in common, LAN and DMZ. This means that
you can configure HA for the LAN network, the DMZ network, or both. You can use
either of the networks as the synchronization interface.
