If the firewall solution shares a logical IP address as part of its
failover  strategy, then I would simply have Nagios monitor that IP address
and wouldn't be too concerned about the physical IP addresses that actually
map to the hosts on which the firewall can run. As long as the logical
address is shown to be the parent of any child services, then the layout in
the status map should be fine.

If you wanted to include the physical IP addresses of the firewalls, then I
guess you could define a host group that contains only both the physical
addresses and then the logical address. Defining only the logical address as
the parent of any other hosts should hopefully sort out the display issues
but I'm not too sure on this.
