Hello guys, some of our users' ISPs don't allow them to use port 25, so they cannot = use out mail server. I want to open a new port (2525) and forward all packets from 2525 to 25 = so, they can use mail. I tried this in IPFW: 0100 119649 44772439 allow tcp from any to me dst-port 25 keep-state 0200 0 0 divert 25 ip from any to me dst-port 2525 = keep-state 0300 103075 35531648 allow ip from me to any keep-state 0400 60 4530 deny log ip from any to any If I telnet directly to port 25, I can get the prompt, but if I telnet = to port 2525, I get a connection refused. What should I do in ipfw to forward port 2525 to port 25 tranparently? Thanks
