    Hi all,

    let me ask you for task "how to control p2p applications and their traffic
    with dynamic ports from user´s commputers on gateway".

    We are small wireless community and have shared access to internet for all
    members. Core members decided to control p2p traffic by default and to allow
    each person in individual way, after showing their knowledge of authorial
    low. :)

    But since many dc hubs, edonkey servers, bittorents web trackers and so on
    use dynamic not standard ports, how to control it ?

    Linux use l7-filter <http://sourceforge.net/projects/l7-filter>
    sourceforge.net/projects/l7-filter sourceforge freeware and , it is based on
    iptables, defination application protocols like ethereal project do.

    So, is there any way to do same application layer osi model firewall with
    FreeBSD gateway ?

    Of course, I tried to find on web, I have not been successful in searching
    so far.

    If my question is not right in this mailing list, if my question is annoying
    here, so I am sorry.

    Dan
