    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

    This is really a question for the vendor of your firewall product.
    If there is some aspect of that firewall product that, as you have
    described, act as a mini IDS and disables all traffic from an IP
    that is seen as scanning the firewall's IPs, then it seems you have
    the choice of using it or not using it if it does not have the ability
    to exempt that you mentioned as needed.
