I'm not positive that this will address your problem, but they may be work a look : bounce-1.0 in the ports collection, from the description there : A little program to bounce tcp connections to another machine/port. By default it listens on port 1523. fwtk-2.1 in the ports collection also has tools for creating firewalls, and I think a method for port fowarding is in there also. I think there may be some license restrictions on it's use. I've never actually used either of these so I can't say if they will do the trick or not. I think there are more than a handle full of programs out there similar to the bounce program listed above. In the past I've successfully used nat to forward requests to other machines, usually on the same port, but that shouldn't make a difference. -- Joseph Scott joseph.scott@owp.csus.edu Office Of Water Programs - CSU Sacramento To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
