In my response I have also added all the steps needed to make this version compilable under windows and vc2010 (in addition to README.win32) 1. remove ref to ..\..\socket\turn.c inside the project (maybe it is an old ref) 2. remove ref to ..\..\socket\tcp-turn.c inside the project (maybe it is an old ref) 3. remove ref to ..\..\socket\tcp-turn.h inside the project (maybe it is an old ref) 4. copy inttypes.h into sln dir 5. replace all inline with __inline 6. add udp_turn.c and udp_turn.h to the project 7. add tcp_active.c and tcp_active.h to the project 8. ad tcp_passive.c and tcp_passive.h to the project 9.add udp-turn-over-tcp.c and udp-turn-over-tcp.h to the project 10.add iostream.c and iostream.h to the project 11.add inputstream.c and inputstream.h to the project 12.add outputstream.c and outputstream.h to the project 13.replace into stun_debug_bytes (debug.c): //char bytes[prefix_len + 2 + (len * 2) + 1]; with: char bytes[1000];//ema and replace snprintf with _snprintf Attached you can find log and wireshark. I can reproduce the problem. The point start from: ** (ewmcu_console.exe:4932): DEBUG: component_io_cb: 020EA018: received -2 valid messages with 0 bytes In my previous test, using the modified code I saw that the reason why the receive function returns -2 is: 10:08:45.063: ema g_socket_receive_message Error receiving message: The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress.: 0 If you set ttl=255, the problem disappears.

Could you possibly attach a full libnice log (run your program with NICE_DEBUG=all G_MESSAGES_DEBUG=all after compiling it with NDEBUG undefined) and a Wireshark log of the problem please? If they’re big, please e-mail them to me personally rather than the entire list. Thanks, Philip </pre> </blockquote> </body> </html>
