title: I can't access a specific port on localhost other than port 80, using my phone
body: <p>On my Windows 10 desktop, I'm running a site on localhost, and another site (Angular 2 if that matters) on localhost:51317.</p>
  
  <p>I'm trying to test it on my phone.</p>
  
  <p>On my iPhone, connected to the same wifi as my computer, I go to my IP address in Safari (example 1.2.3.4), and it successfully loads port 80.</p>
  
  <p>But if I go to 1.2.3.4:51317, I get no response. Safari could not open the page because the server stopped responding. But on my computer, localhost:51317 works).</p>
  
  <p>What I've tried:</p>
  
  <ol>
  <li>In Windows Firewall, I added an Inbound Rule for port 51317 (TCP) (Port, 51317, Allow the connection, Apply to: Domain, Private, Public)</li>
  <li>Added an Inbound Rule for UDP 51317 as well</li>
  <li>I disabled Windows Firewall</li>
  </ol>
  
  <p>None of these let my phone access 51317, but I could access port 80.</p>
  
  <p>If it's relevant, that site is Angular 2 on .NET backend.</p>
