        this has nothing to do with Qt, going through NATs is a killer.

              again, p2p through NAT is a KILLER, and you obviously have no clue what you're up against. take a look here: http://p2p-os.blogspot.com

                  what is the ip address assigned to each client ? Also if it through NAT Qt has no role to play.

                    i have a server ,it has a public IP, clientA and clientB send a message to server ,server records clientA and clientB's ip and port from udpsocket.
