I'm using ipfw on 4.5-Release. I have created a rule set based on the rc.firewall.current script found at http://www.bsdtoday.com/2000/December/Features359.html and have been using it successfully for several months. Passive FTP transfers initiated from the inside will work through the firewall just fine. However, active transfers do not. I'd like to get active transfers working so that my backup software can update its virus protection data files without my intervention. Is there a rule I can add to open port 20 when I initiate a FTP transfer? I have seen the punch_fw option in natd but I am not using natd (NAT is handled by my DSL modem/router). I've searched Google but have not found a definitive answer although I suspect I can not do what I want. Can anyone confirm or deny my suspicions?
