I have some machines behind a freebsd firewall, and I'm using ipfw. Presently, I reset attempts to smtp past the firewall:
reset tcp from [subnet] to any 25 but I'd like to divert them to my own smtp server, so it doesn't matter what the clients try to use. I thought this would be easy. Maybe it is. The "fwd" feature doesn't seem to do it, as it just forwards a specific ipaddr[,port] (no subnet/mask) "divert" looks like the way to do it, and after a few hours of fiddling with a program that opens a divert socket, I can watch all manner of traffic going back and forth, but each time I attempt to send it elsewhere, I get nowhere. I am duly setting both the ip and tcp checksum, before re-injection. Somebody else must have done this, and/or I must be doing it the wrong way. Any suggestions ? Please e-mail me directly also as I am not on this list. A code snippet using divert would be excellent. -- Bruce Campbell Engineering Computing CPH-2374B University of Waterloo (519)888-4567 ext 5889 ---------------------------------------- This mail sent through www.mywaterloo.ca _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
