Program (PortTunnel) that sends CONNECT to proxy runs on port 2000. It does same thing as http-proxy parameter in OpenVPN, but with this parameter I had problems.

The IRP Queue handles the packet flow from the TAP driver to the userspace component of OpenVPN. Not sure why this would occur, though your config files might shed some light.

After connection establishing work pinging OK, but when I try connect from server to client with VNC or Remote Desktop Connection (from Microsoft) it is working for few seconds (first screen loaded) and then stops working all TCP/IP communication (pinging doesnt work). On side of client it generates this error (on server side it is no error): > > Mon Dec 08 18:11:57 2003 672: TCPv4_CLIENT link local: [undef] Mon Dec > 08 18:11:57 2003 673: TCPv4_CLIENT link remote: 127.0.0.1:2000 Mon Dec > 08 18:11:57 2003 674: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:57 2003 675: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:57 2003 676: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:57 2003 677: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:57 2003 678: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:57 2003 679: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:57 2003 680: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:58 2003 681: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:58 2003 682: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:11:58 2003 683: read from TUN/TAP [State=AT?c Err=[c:\src\openvpn\tap-win32\tapdrvr.c/1756] #O=5 Tx=[315,0] Rx=[0,0] IrpQ=[16,16,16] PktQ=[0,10,64]]: General failure (ERROR_GEN_FAILURE) (code=31) > Mon Dec 08 18:12:27 2003 684: 269 variation(s) on previous 10 > message(s) suppressed by --mute > Mon Dec 08 18:12:27 2003 685: Connection reset, restarting [0] Mon Dec > 08 18:12:27 2003 686: Closing TCP/UDP socket Mon Dec 08 18:12:27 2003 > 687: Restart pause, 3 second(s) > > > Anyone knows, where could be a problem? > > Thanks > Wally > > > ------------------------------------------------------- > This SF.net email is sponsored by: SF.net Giveback Program. > Does SourceForge.net help you be more productive?
