HI, I wanted to know how gtalk opens up a pinhole on NAT. I gave my friend my public IP address and asked him to send a TCP connection request for this public IP address and the port(say 25555) that I opened in my PC. But I had to open the port(25555) in my modem for the TCP request to reach me.
Using STUN we can obtain the public IP address and port number from which the packet entered public Internet. If I send this(both public IP and public port number) to my friend, can he send a TCP connection without me opening a port in my modem?? Does STUN work for symmetric NATs? Does gtalk use STUN? If gtalk does not use STUN what mechanism does it use? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "google-talk-open" group.
