关于使用streem.pipe实现反向代理的一个问题

参考了用nodejs实现反向代理远程桌面（外网连接局域网内机器实现远程）http://yoyo.play175.com/p/proxyrdp.html

写了一段简单的实验:

var net = require('net');
var client_port = 8889;
var host = '127.0.0.1';
host = '192.168.7.69'; 

var client = net.createServer(function(c) {
    var loc = net.connect(3389, host, function() {
      console.log('本地远程桌面 3389 连接成功！');
      loc.pipe(c);
      c.pipe(loc);
    });
}).listen(client_port, host, function(c) {
  console.log('代理已开启,托管为: %j',client.address());
});

执行后输出:

E:\Workspace\Code\SmartDoor>node test.js 代理已开启,托管为: {"address":"192.168.7.69","family":"IPv4","port":8889} 本地远程桌面 3389 连接成功！

但是用win自带的远程桌面,连接一直超时。本机远程桌面已开，本机连接本机也上不了。请教下是哪步遗漏了？

多谢YOYO的指点, 解决了. 调换下顺序即可.

var net = require('net');
var client_port = 8889;
var host = '127.0.0.1';
host = '192.168.7.69'; 

var client;
var loc = net.connect(3389, host, function() {
  console.log('connet to 3389 success.');
  client = net.createServer(function(c) {
    loc.pipe(c);
    c.pipe(loc);
  }).listen(client_port, host, function(c) {
    console.log('proxy opened, visit: %j',client.address());
  });
});
