I once wanted to do something similar by have two bridging firewalls (see
bridge(4) and the BRIDGE_IPF option). By using stp, only one would be
active at any time and STP (spanning-tree protocol) would take care of
failover. But I never did it (one firewall was reliable enough) so I do
not know if it works.
