Connecting 2 android devices over internet

Hi I'm trying to connect 2 android device (without server in the middle, just directly like peer-to-peer) which are connected to internet(they are far apart) and send messages.
I thought its like normal socket programming, and connects via IP, seems not.

what I have done so far is this:
I have created 2 android projects, server(receiver) and client(sender) running in 2 separate devices
Both devices are connected to internet
found the IP of the device with server app running in (using whatismyip.com) and used it in client app code
but when I want to send a text from client to server, an exception happens in client printing Error3

this is my code:
server:

public class MainActivity extends Activity {

	   ServerSocket ss = null;
	   String mClientMsg = "";
	   Thread myCommsThread = null;
	   protected static final int MSG_ID = 0x1337;
	   public static final int SERVERPORT = 6000;

	   @Override
	   public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		TextView tv = (TextView) findViewById(R.id.TextView01);
		tv.setText("Nothing from client yet");
		this.myCommsThread = new Thread(new CommsThread());
		this.myCommsThread.start();
	   }

	   @Override
	   protected void onStop() {
		super.onStop();
		try {
			// make sure you close the socket upon exiting
			ss.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	   }

	   Handler myUpdateHandler = new Handler() {
		public void handleMessage(Message msg) {
			switch (msg.what) {
			case MSG_ID:
				TextView tv = (TextView) findViewById(R.id.TextView01);
				tv.setText(mClientMsg);
				break;
			default:
				break;
			}
			super.handleMessage(msg);
		}
	   };
	   class CommsThread implements Runnable {
		public void run() {
			Socket s = null;
			try {
				ss = new ServerSocket(SERVERPORT );
			} catch (IOException e) {
				e.printStackTrace();
			}
			while (!Thread.currentThread().isInterrupted()) {
				Message m = new Message();
				m.what = MSG_ID;
				try {
					if (s == null)
						s = ss.accept();
					BufferedReader input = new BufferedReader(new InputStreamReader(s.getInputStream()));
					String st = null;
					st = input.readLine();
					mClientMsg = st;
					myUpdateHandler.sendMessage(m);
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	    }
	}

Client:

public class MainActivity extends Activity {

	   private Button bt;
	   private TextView tv;
	   private Socket socket;
	   private String serverIpAddress = "5.114.22.118";
	   // AND THAT'S MY DEV'T MACHINE WHERE PACKETS TO
	   // PORT 5000 GET REDIRECTED TO THE SERVER EMULATOR'S
	   // PORT 6000
	   private static final int REDIRECTED_SERVERPORT = 80;
	   
	   @Override
	   public void onCreate(Bundle savedInstanceState) {
	      super.onCreate(savedInstanceState);
	      setContentView(R.layout.activity_main);
	      bt = (Button) findViewById(R.id.myButton);
	      tv = (TextView) findViewById(R.id.myTextView);
	      
	      new Thread(new ClientThread()).start();
	      
	      bt.setOnClickListener(new OnClickListener() {
	         public void onClick(View v) {
	            try {
	               EditText et = (EditText) findViewById(R.id.EditText01);
	               String str = et.getText().toString();
	               PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
	               out.println(str);
	               Log.d("Client", "Client sent message");
	            } catch (UnknownHostException e) {
	               tv.setText("Error1");
	               e.printStackTrace();
	            } catch (IOException e) {
	               tv.setText("Error2");
	               e.printStackTrace();
	            } catch (Exception e) {
	               tv.setText("Error3");
	               e.printStackTrace();
	            }
	         }
	      });
	   }
	   
	   class ClientThread implements Runnable {
		
		   @Override
	       public void run() {
			   try {
			         InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
			         socket = new Socket(serverAddr, REDIRECTED_SERVERPORT);
			      } catch (UnknownHostException e1) {
			         e1.printStackTrace();
			      } catch (IOException e1) {
			         e1.printStackTrace();
			      }
		   }
	   }
        
	}
