    Hi ,
    I am developing a firewall for windows operating system . I am facing a problem while handling RDP ,
    Although I have set a rule for RDP to allow tcp Packets on port 3389 but but It is not working .
    I am using winpkfilter driver to get packets , I am getting the packets and doing some processing .
    When I dont do any processing it works fine but as I start processing my RDP connection breaks.I think as I
    queue the packets for processing in between i am loosing some packets. I am not able to analyze the
    problem . Can any body help me regarding this?

    Thanks

    It may happen if your packet processing code is incredibly slow. In this case internal driver packets queue reaches its maximum size and all newly coming packets are dropped.

    If you use high speed connection I recommend to use ReadPackets API instead ReadPacket (refer PackThru sample) and optimize your packet processing code.
