    Hi,

        I am Using Win2003 Server as a DataBase Server For Both Internal Access
    (LAN) and Internet Web Server Access (Though an External Internet Host) , I
    installed a Firewall Software to prevent any access to ports other that the
    SQL-Server Port 1433 and Any Application Other Than SQL-Server

        I have an Internal Web Application On The Main Server ( win2k3) which is
    intended to access the database server to get/post data

        everything goes fine untill the main server tries to portscan the
    database server , then the firewall response by blocking traffic from the
    main server

        I need help in this

        AND

        I think If Know the protocol AND/OR application that responds or
    detects portscanning I would open only this kind of traffic to the local
    server , and block this kind of traffic from any other place , unfortunatly
    the firewall can enable/disable port scan detection of the entire system ,
    not to a specfic IP

        HELP

        Thank You
