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.
The procedure below shows how to configure HA for both the LAN and DMZ networks.
The synchronization interface is the DMZ network, the LAN virtual IP address is
192.168.100.3, and the DMZ virtual IP address is 192.168.101.3. Gateway A is the Active
Gateway.
To configure HA for Gateway A and Gateway B
1. Connect the LAN port of Gateways A and B to hub 1.
2. Connect the DMZ port of Gateways A and B to hub 2.
