How to Connect Using Socket From Ip Like 72.55.168.241 to 192.168.1.3 (Windows App)

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

            finally
            {
            }
        }

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();
            }
