title: peerjs with STUN for webrtc
body: <p>I have developed a webrtc based video chat using peerjs. The solution is working fine but some users are facing problem to establish the call. I guess it is due to NAT and firewall issues. </p>
  
  <p>I have user peerjs as :</p>
  
  <pre><code>var peer = new Peer({host: myserver.com], port: 9000, debug: true});
  </code></pre>
  
  <p>I have changed the code to <code>[passed google stun]</code> as seen here : <a href="https://groups.google.com/forum/#!msg/peerjs/JzIr7INoTbQ/IIykVNHiv_sJ" rel="nofollow">https://groups.google.com/forum/#!msg/peerjs/JzIr7INoTbQ/IIykVNHiv_sJ</a> </p>
  
  <p>Still the same issue. Some user can not connect to peer id.
  Am I doing something wrong?</p>
