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 ;) Martin
