title: Domain name for my PC: how to (tried No-IP, DuckDNS and ngrok)
body: <p><strong>I want:</strong> ping server on my PC by it domain name from remote.</p>
  
  <p><strong>I have:</strong> </p>
  
  <ol>
  <li>DynDNS services <a href="http://duckdns.org/" rel="nofollow">DuckDns</a> (or <a href="http://www.noip.com/" rel="nofollow">No-IP</a>, config in no-ip is even harder). It gets me an IP <code>94.154.220.216</code> and (sub)domain <code>http://my_domain.duckdns.org</code>. To configure <code>DuckDNS</code> on PC I need just specify some token and my domain name (<code>my_domain</code>). </li>
  <li>Also I've launched server on <code>lacalhost:3000</code>. </li>
  <li>Also when I go to <a href="http://www.canyouseeme.org/" rel="nofollow">CanYouSeeMee</a> it says that my IP is <code>94.154.220.216</code> (that's good).</li>
  <li>And I configured static IP for my PC (let's say <code>200.300.1.15</code>)</li>
  <li>And Setting port forwarding for with help of <a href="http://www.macupdate.com/app/mac/46424/port-forwarding-wizard" rel="nofollow">Port Forwarding Wizard</a> (Port=<code>3000</code>, Protocol=TCP, Internal IP = <code>200.300.1.15</code>)</li>
  </ol>
  
  <p><strong>Problem:</strong> I can't get neither <code>http://my_domain.duckdns.org</code> nor <code>http://my_domain.duckdns.org:3000</code> from remote. </p>
  
  <p><strong>Assumption:</strong> I assume that troubles are in router configurations.</p>
  
  <p><strong>Questions:</strong></p>
  
  <ol>
  <li><em>How can I check what is wrong?</em> Means whether DuckDNS doesn't redirect request to my router or my router don't redirect request to my PC.</li>
  </ol>
  
  <p><strong>My local network scheme:</strong></p>
