    Hi all,

    Dear friend,
    In a huge networking traffic , there might be a chance of entering the sent packet to the wrong destination ,so we can find the problem at least in the TCP layer.

    For further references : Refer TCP/IP guide

    The "exact problem" is that you get an incorrect checksum. Simple as that.
