title: Listen on 127.0.0.1 instead of 0.0.0.0 in bundled meteor app
body: <p>I've bundled my meteor app and running it via "node main.js", how can I tell Node to listen on 127.0.0.1:3000 instead of 0.0.0.0:3000?</p>
  
  <p>When I was using "Meteor run", I could use "Meteor run --port host:port" to specify the interface.</p>
  
  <p>Here you can see the difference:</p>
  
  <pre><code>$ MONGO_URL=mongodb://localhost:27017 PORT=3000 ROOT_URL=http://localhost/ node main.js
  
  $ sudo netstat -anp                     
  tcp        0      0 0.0.0.0:3000            0.0.0.0:*               LISTEN      3126/node       
  </code></pre>
  
  <p>vs.</p>
  
  <pre><code>$ meteor run --port 127.0.0.1:3000
  $ sudo netstat -anp
  tcp        0      0 127.0.0.1:3000          0.0.0.0:*               LISTEN      3342/node 
  </code></pre>
