    Dear all,

    Thanks for your suggestions. May be I am not able to define my question
    properly.

    This problem is strictly with in company internet access firewall and in the
    LAN only. In a company, policy for Internet access says it is through IP
    only. The others can not browse the internet. This policy is implemented on
    firewall. Few smart guys have installed free proxy server running on non
    default ports and distributed the internet access to their friends. The
    firewall sees the traffic coming from the authorized IP and does not stop
    them. We want to know who has installed proxy on there machine.

    I hope, I am able to clearly define my question. Thanks

    vinay
