title: How can I access a vagrant guest from another virtualbox guest?
body: <p>The scenario is that my dev environment is on a Vagrant box on my laptop (host) and I would like to do browser testing in a vitualbox vm, so I need to see one vm from another. </p>
  
  <p>The vagrant box's port is :8080 which is forwarded to the host on the same port :8080. So I can see the server from the host at localhost:8080</p>
  
  <p>Which address should I be using for the browser testing vm?</p>
  
  <p>The testing vm's default gateway?
  The vagrant vm's ip?
  The host's virtual network ip?</p>
  
  <p>And should I be using a NAT or host only adapter on the browser testing vm?</p>
  
  <p>That makes for a lot of combinations, all of which I believe I have tried. What else do I need to understand here? </p>
