When I said similar, I alone placed ips representative therefore script that I passed for you. The other rules are alone to open gate of web and ftp. Therefore I didn't pass orders rules because would not indicate nothing about email. :P > I recommend again that you look at "ipfw show" to see what rules are > catching packets.

The script work ok for all rules but less for email. Or either, when I do ready the firewall, all the ports that I free is ok, except the email . :( Thus, when a person tries to have access for example a hp it's ok, but when it tries to send email it fails. :( > Also, did you say that it DOES WORK when the firewall is disabled? When I put the rules "allow all from any to any" the email serve send msgs. Some rule of that I passed you is stopping the access of the email or It is necessary to open some another port.
