title: Ubuntu: Can't connect to host's internet connection using NAT
body: <p>I installed Lubuntu on Virtualbox.  I'm using Windows 7 x64.  My VM is 32 bit version.  The internet works using Bridged Adapter, but I'm trying to use NAT so I can use a VPN.  In Network and Sharing Center in Windows, I see connection "VirtualBox Host-Only Connection" and it says "No Internet Access".  In properties, "VirtualBox Bridged Networking Driver" is checked.  The following is the output of ifconfig:</p>
