thank u very very much for u r reply...

There are more than one IP in Address List and system (e.g computer) use one IP at a time, then can u give me the idea how to detect which is the primary IP (means which IP is Currently using).

thank u sir.
You want to know why i need this. Please read the following line carefully specially point No. 3.I want to implement this, that why i need to use the same port.

Suppose that client A wishes to set up a TCP connection with client B and both are behind the NAT. We assume as usual that both A and B already have active TCP connections with a well-known rendezvous server S. The server records each registered client's public and private endpoints.

1. Client A uses its active TCP session with S to ask S for help connecting to B.
2.S replies to A with B's public and private TCP endpoints, and at the same time sends A's public and private endpoints to B.

3.From the same local TCP ports that A and B used to register with S, A and B each asynchronously make outgoing connection attempts to the other's public and private endpoints as reported by S, while simultaneously listening for incoming connections on their respective local TCP ports.

4.A and B wait for outgoing connection attempts to succeed, and/or for incoming connections to appear. If one of the outgoing connection attempts fails due to a network error such as “connection reset” or “host unreachable,” the host simply re-tries that connection attempt after a short delay (e.g., one second), up to an application-defind maximum timeout period.

5.When a TCP connection is made, the hosts authenticate each other to verify that they connected to the intended host. If authentication fails, the clients close that connection and continue waiting for others to succeed. The clients use the first successfully authenticated TCP stream resulting from this process.

i already try this.
thanks.

i also face such problem.
part of my code:

//Connect RemoteEndPoint
//this Remote IP is 72.55.168.241

private void ConnectRemoteEndPoint()
{
TcpClient tcp_RemoteEndPoint=new TcpClient();
IPAddress ipAddr = IPAddress.Parse(192.168.1.3);
try
{
tcp_RemoteEndPoint.Connect(ipAddr, 2000);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

//Accept RemoteEndPoint
//This Remote IP 192.168.1.3

private void AcceptRemoteEndPoint()
{
TcpListener listener_tcp;
TcpClient tcp_Remote;
listener_tcp = new TcpListener(IPAddress.Parse(192.168.1.3), 2000);
listener_tcp.Start();
while (true)
{
tcp_Remote= listener_tcp.AcceptTcpClient();
}
)

Error comes from ConnectionRemoteEndPoint() function:

Error: A request to send or receive data was disallowed because the socket is not connected and ( when sending on datagram socket using sendto call)and no address was supplied.

So, you mean to say that every time you use Yahoo messenger, GTalk, Skype etc., you have to configure the Router. Hey Jim the problem is something else.

To clarify he above posted question: Both machines communicate using a socket server over the Internet. Although the machines have unique IP in the LAN, but the main problem is that, both the machines have same IP on the Internet. And Sockets communicate only through IP and PORT, so how will we distinguish which machine is requesting what??? Note, I am taking about the problem, only when communicating over the Internet, and you can find each machines Internet IP using tools like (whatsmyip.com etc). Here the communication issue arises. Any help will be highly appreciated.
