title: Homestead cant access second site remotely
body: <p>I have one site setup fine, but the second can't be accessed remotely:</p>
  
  <p>My YAML:</p>
  
  <pre><code>---
  ip: "192.168.10.10"
  memory: 2048
  cpus: 1
  provider: virtualbox
  
  authorize: ~/.ssh/id_rsa.pub
  
  keys:
      - ~/.ssh/id_rsa
  
  folders:
      - map: ~/Projects
    to: /home/vagrant/Projects
  
  sites:
      - map: app.app
        to: /home/vagrant/sites/app1/public
      - map: app2.app
        to: /home/vagrant/sites/app2/public
        port: 8100
  
  ports:
      - host: 81
      - guest: 8100
  </code></pre>
  
  <p>I can access the first site using my IP easily - <code>http://192.168.0.5/</code> but the second one cannot share the same port, so I've added <code>81 -&gt; 8100</code>.</p>
  
  <p>When I try to reprovision my homestead vagrant box it says:
      There are errors in the configuration of this machine. Please fix
  the following errors and try again:</p>
  
  <pre><code>vm:
  * Forwarded port definitions require a "host" and "guest" value
  * Ports to forward must be 1 to 65535
  * Ports to forward must be 1 to 65535
  </code></pre>
  
  <p>Any ideas?</p>
