title: Accessing ngrok web interface on a Vagrant box
body: <p>I have a Vagrant box I'm using for local development. I'm working on a webhook, which is being called from outside; so I'm thinking of using ngrok.com to proxy requests to my Vagrant environment. I'm new to this ngrok thing.</p>
  
  <p>I'm trying to figure out how to access ngrok's web interface, which is normally at <a href="http://127.0.0.1:4040" rel="noreferrer">http://127.0.0.1:4040</a>. Of course, that doesn't work from my browser, because it's outside of the Vagrant box, so its localhost is not the Vagrant's localhost.</p>
  
  <p>I (think I) have the Vagrant's IP address. I found it in a config.yaml file (yes, with an a), under vm: network: private_network: 192.168.nnn.nnn</p>
  
  <p>Thanks for your help.</p>
