I use ipfilter, which comes with 3.* although I am not using that version for historical reasons (I swapped to ipfilter back on 2.2.7 I think). I think it does what you want with the exception of the DCC send from inside the firewall. Receives are fine. The problem is the DCC protocol standard. You could use something like the BNC proxy to get around that issue. I've also seen mention of an ipproxy in the ipfilter mailing lists, but I haven't followed it up. Perhaps putting a question to that list might help (ipfilter@coombs.anu.edu.au) but I think you must be subscribed to send to the list ==> Send mail to majordomo@coombs.anu.edu.au with "subscribe ipfilter" in the body of the mail. That said, I'm *told* but have not investigated the features of natd which allow DCC to work unhindered by NAT. See http://www.freebsddiary.com/freebsd/dcc.htm for what I was told. hth -- Dan Langille - DVL Software Limited The FreeBSD Diary - http://www.FreeBSDDiary.org/freebsd/ NZ FreeBSD User Group - http://www.nzfug.nz.freebsd.org/ The Racing System - http://www.racingsystem.com/racingsystem.htm To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
