    I Group,

    If I change the first Web Browser rule:
    accept, Protocol-->0, Access Network for
    accept, Protocol-->match inverted NetBios, access Network

    Protocol-->0, mean without any protocol?

    Is it mean, if I choose Protocol-->match inverted Netbios, it will give access to they other protocol except Netbios and in the same time with the access network?

    Is it will be good or not good?

    Thank.

    Hi Mido,
    I presume you are refering to "Jetico"?

    I see you are thinking of the "protocols". Netbios is within layer 6 which is actually handled in the user tables, that give the binding of packet to application.

    Jetico does not give such as protocol "Netbios",.. please re-check. You may find "netBEUI", which is layer 5.

    Stem,

    I saw in a german tutorial.
    Placing the rule:-> reject, protocol:match inverted->NetBios, access to network
    before (I suppose) the usual rule:-> accept, Protocol:0, access to network.
    But when I tried this, Firefox couldn't have a connexion.

    Then, I would like for knowing, if I replace the first usual rule in Web Browser by:
    accept, protocol:match inverted->NetBios, access to network.
    I suppose it will be not good because it will let pass all other protocol except Netbios into the acces to network.

    Confirmation?


    Thank.
