What prevents you from picking one source address for packets going out both interfaces? Your return packets won't be striped then of course. (Which could make this scheme ineffective, assuming "client" machines receive much more than they send.) (Aside: Whether or not NAT is present is orthogonal to striping, just assume the NAT box is the source/sink for all traffic.) > On a per session basis, you may be able to work with ipfw fwd > (which does policy based forwarding) and the ipfw probability work > done by Luigi. man ipfw for more info. I didn't know about that, thanks for the pointer! I use ipfw strictly as a firewall :-) Lars -- Lars Eggert <larse@isi.edu> Information Sciences Institute http://www.isi.edu/larse/ University of Southern California To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
