This Layer 3 interface example uses
NAT
in Active/Active HA Mode and
ARP
Load-Sharing with destination NAT. Both HA firewalls respond
to an ARP request for the destination NAT address with the ingress
interface MAC address. Destination NAT translates the public, shared
IP address (in this example, 10.1.1.200) to the private IP address
of the server (in this example, 192.168.2.200).
