    I try to do delay authorization at FWPM_LAYER_ALE_AUTH_CONNECT_V4/6 for multicast datagrams

    On windows 7 FwpsInjectTransportSendAsync0 works well, but on windows 8 datagrams are not sent. What have I missed?

    Bug is reproducing 50 / 50. I tried  to insert a 100ms delay into my worker routine. With this delay bug is not reproduced. I think, there is an interop with work thread which try to join to multicast ( tcpip!IppMulticastWorkerRoutine ). The main problem is the callout driver failed HCK test "Winsock Core Functional Test" with reason: "The test logs show that all UDP multicast datagrams are being dropped for both IPv4 and IPv6 tests"
