PA-3050-1 has Device ID 0 and its
HA peer, PA-3050-2, has Device ID 1. In this use case, NAT translates
the source IP address and port number to the floating IP address
configured on the egress interface. Each host is configured with
a default gateway address, which is the floating IP address on Ethernet1/1
of each firewall. The configuration requires two source NAT rules,
one bound to each Device ID, although you configure both NAT rules
on a single firewall and they are synchronized to the peer firewall.
