title: Can't reach Vagrant box over public network
body: <p>I want to be able to use computer 1 (iMac) to a view a site on a Vagrant Box (running a LAMP stack in my case) on computer 2 (Macbook) over a Wifi connection (AirPort/Timecapsule), but I just cannot get this working. Both computers are on the same network.</p>
  
  <p>As I understand it, adding the line:</p>
  
  <pre><code>config.vm.network "public_network", ip: "192.168.XX.XX"
  </code></pre>
  
  <p>and choosing Wifi (AirPort) from the list that the vagrant reload -commands presents, should make the virtual machine available to computer 1 over the network. Hence hitting <code>http://192.168.XX.XX/mysite</code> from computer 2 should present the site.</p>
  
  <p>Trying this however ends with the browser giving me a timeout error. What could be wrong? Everything works just fine while viewing the site on the host machine (computer 2) when running the same line but with <code>"private_network"</code> instead.</p>
  
  <p>I'm running vagrant 1.6.5</p>
