[JS] TCP Proxy ports.

[Mega Byte]

A basic TCP port proxy can be used for nearly all TCP traffic? I dunno.
It was just an idea I had to help mitigate some ddos by having many servers and hiding the real ip of the server using this then we could monitor each one and filter or turn them off as needed etc.

var net = require('net');

function ProxyServer(localport, remoteip, remoteport) {
  if (remoteport === undefined) remoteport = localport;
  var server = net.createServer({
    allowHalfOpen: false,
    pauseOnConnect: false
  }, function connected(a) { //'connection' listener
    console.log('client connected '+localport);

    var b;

    a.on('end', function() {
      console.log('client disconnected '+localport);
    });


    var b = net.connect(remoteport, remoteip,
      function() { //'connect' listener
      console.log('connected to server '+remoteport);
      a.resume();
      a.pipe(b);
      b.pipe(a);
    });

    b.on('end', function() {
      console.log('disconnected from server '+remoteport);
      a.close();
    });
    
  });

  server.listen(localport, function() { //'listening' listener
    console.log('server bound '+localport);
  });

}

// Put your ports here
var ports = [****];
// Put your ip here
var serverip = '***.***.***.***';

var proxies = [];
for (var i=0;i<ports.length;i++) {
  var p = new ProxyServer(ports[i], serverip);
  proxies.push(p);
}

// TODO Clean exit.
