How to forward UDP? about jtun2socks HOT 4 OPEN

        `DatagramSocket clientSocket = new DatagramSocket();
        byte[] response = new byte[256];
        InetSocketAddress destination = new InetSocketAddress("1.1.1.1", 1080); //EDIT THIS WITH THE IP AND PORT OF THE PROXY

        Socket socketProxy = new Socket();
        socketProxy.bind(new InetSocketAddress(0));
        service.protect(socketProxy);
        socketProxy.setSoTimeout(5000);
        socketProxy.connect(destination, 5000);

        DataOutputStream writer = new DataOutputStream(new BufferedOutputStream(socketProxy.getOutputStream()));
        DataInputStream reader = new DataInputStream(new BufferedInputStream(socketProxy.getInputStream()));

        // connect/authorization request
        writer.writeByte(0x05); // VER
        writer.writeByte(0x01); // NMETHODS
        writer.writeByte(0x00); // METHODS
        writer.flush();

        // connect/authorization response
        reader.read(response); // RESPONSE IS: 5 0

        // udp associate request
        writer.writeByte(0x05); // VER
        writer.writeByte(0x03); // CMD - UDP ASSOCIATE
        writer.writeByte(0x00); // RSV
        writer.writeByte(0x01); // ATYP
        // is what I'm sending here as DST.ADDR & DST.PORT okay?
        writer.write(clientSocket.getLocalAddress().getAddress()); // DST.ADDR
        writer.writeShort(clientSocket.getLocalPort()); // DST.PORT
        writer.flush();

        // udp associate response
        Log.d(TAG, "udp associate response");
        reader.skipBytes(4); // skip VER, REP, RSV, ATYP bytes
        int relayAddress = reader.readInt();
        InetAddress relayInetAddress = InetAddress.getByAddress(ByteBuffer.allocate(4).putInt(relayAddress).array());
        int relayPort = reader.readUnsignedShort(); // server returns some random port

        // connect to relay server via datagramsocket
        clientSocket.connect(relayInetAddress, relayPort);`
