title: VirtualBox Linux does not return ping and host machine cannot access apache on that guest
body: <p>I have a Windows7 as host and Debian as guest via VirtualBox. everything worked just fine until I did <code>apt-get update</code> on my guest machine and I think it scrambled some settings (not sure though...).</p>
  
  <p>My current VB network settings are: </p>
  
  <p>Adapter 1: Bridged Adapter</p>
  
  <p>Adapter 2: Host-only adapter</p>
  
  <p>My guest machine works fine, has internet connection and I can access it files via <code>My Computer &gt; Network</code>, yet I cannot ping the guest machine nor access its apache webserver, any ideas?</p>
