More details please!

You need to create a tunnel to bridge your LAN firewall and open ports on the WAN interface.

Most routers have a "virtual server" configuration for this which will map a port to an internal LAN server and port number.

Sending and receiving you can do with the TcpClient class.

how in tcpclinet
TcpClient tcpclnt = new TcpClient("", 8001);

NetworkStream mynetsream = tcpclnt.GetStream();
StreamWriter myswrite = new StreamWriter(mynetsream);
myswrite.WriteLine(TextBox1 .Text );
//System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
//byte[] bt=encoding.GetBytes(TextBox1.Text.ToString ());
//EndPoint ourEP = new IPEndPoint(IPAddress.Any, 8001);
//tcpclnt.Client.SendTo(bt, ourEP);
