    I’m currently trying out NeT Firewall and I like it alot so far.
    I do have some questions.

    On the server in trying out NeT Firewall on, one network card has 40 extrernal IP’s. If I add a rule allowing external access to one of those IP’s, all the others get accessable too. Why is that?

    I’m having trouble with the FTP server and passive ports. I added ports 20,21 TCP and the passive port range specified in the ftp server. When i try to connect using passive mode in the client the passive ports still don’t accept connections. Any idears?

    Could someone please list a standard ruleset for allowing all traffic to port 80 on the server only. I know it’s very basic but it would be great to make sure I did it right.

    I found a few bugs playing about. Are you interested in fixing then if i detail the issues?

    Thanks in advance!

    I managed to fix my passive mode problem in the client. Had to mark PASV 3 places .. 🙄

    I would still appriciate help with the other issues.

    It should not be, probably the rule you create is too common and covers more than one IP.

    Allow, TCP, Source IP: Any, Source Port: Any, Destination IP:[IP address your WWW server is bound to], Destination Port:80 Bidirectional.

    Also set the security level to high.

    Sure, if you find any bugs we would appreciate reporting about…
