RemoteEndPoint: Identifying the client from the server side

Variant 1: When using TcpListener class for our server there are 2 ways to get the underlying client

TcpClient client = listener.AcceptTcpClient();

IPEndPoint remoteEP = (IPEndPoint) client.Client.RemoteEndPoint;

Socket client = listener.AcceptSocket();

IPEndPoint remoteEP = (IPEndPoint) client.RemoteEndPoint;

Variant 2: When using the Socket class:

Socket client = socketServer.Accept();

IPEndPoint remoteEP = (IPEndPoint) client.RemoteEndPoint;

Then we can very easy get the IPAddress/Port for the client

IPAddress ip = remoteEP.Address;

int port = remoteEP.Port;

I am developing a Client-Server application using TCPLister and TCPClient(sockets). I used the below code. It works fine when I create a TCPListener using local m/c’s IP Address. However, it doesn't work if I used other than that.(public IP address). ----------Code Start ----------- IPAddress ipAddress = System.Net.IPAddress.Parse("202.1.25.124"); TcpListener tcpServerListener = null; try { //create server's tcp listener for incoming connection tcpServerListener = new TcpListener(ipAddress, 3333); tcpServerListener.Start(); //start server } catch (System.Net.Sockets.SocketException ex) { Console.WriteLine(e.StackTrace); } ----------Code End ----------- It throws socket Exception saying at this line tcpServerListener.Start(); -- {"The requested address is not valid in its context"} Can I create a TcpListener on m/c other than localhost? -----------------------------------------------------------***************************************************-------------------------------------------------------------------- Mariya, any help will be highly appericiated ! Thanks, Amol Gholap Iotap, India

This might be a dumb question but are you sure the IP address has been assigned properly?
