Why doesn't the code work correctly?

Question

Node.js

var net = require("net");
var portIn = "6065",
    hostOut = "127.0.0.1",
    portOut = "6080";

var connection=true;
net.createServer(function(connIn) {
  console.log('camera: ' + connIn.remoteAddress +':'+ connIn.remotePort);
    var mycallback=function(connOut){
            console.log('client: ' + connOut.remoteAddress +':'+ connOut.remotePort);
            connIn.pipe(connOut);
            connOut.pipe(connIn);
            connection=false;
            connOut.on("end", connIn.end.bind(connIn));
            connIn.on("end", connOut.end.bind(connOut));
            connOut.on("error",function(err){console.log(err)});
            connIn.on("error",function(err){console.log(err)});
    }
    if(connection){
        var server = net.createServer(mycallback);
        server.listen(portOut);
    }
}).listen(portIn);

There is a code, some attempt to make a functional similar to This miracle in SI , when you try to forward the port, nonsense occurs, say port 80, if you forward, I get a clumsy layout. What else could be the matter, I use the same client part as with the git
