I don't have any experience yet with it but I'm planning on using CARP
with PF to do redondant gateways. You can do round-robin RDR with PF to
distribute the load. You can even put the same server IP more than one
time in the list to forward more traffic to this server! I tested it but
I didn't tried CARP yet.
I read I couple of articles on CARP with BSD, I'm a little bit surprised
that nobody made reference to it yet. Now it's done ;)
