Some web sites (e.g. YouTube) don't seem to work well with NAT based load-balancing. Check out sticky-address options in PF, which might help that. Also, to achieve reliable fail-over look at using ifstated. Check the mail archive for examples. Finally, 172.17.1.0 isn't a legit address to listen on. -Steve S.
