With a vanilla install of Ubuntu 12.04 on a vanilla install of Virtual Box with NAT on VB, my network settings seem to function incorrectly.
What baffles me is that I can
ping www.google.com, but I can't

I am on a corporate network, so there might be firewall issues or other security settings that I am unaware of. But I find it strange that I sould be able to ping and not access http, since I can do both on the host system (Windows).
Amongst other questions:
- should I assign the same MAC address to this virtual interface as the actual MAC address of the host's NW interface? Is this good or bad practice?

Is is possible that my VBox installation might be incomplete? I do not have admin rights to my host system. The installation seems to have gone well (I can install and run a virtual machine), but everytime I boot it tries to install something that I cannot identify (in true Windows style) and requires admin access, which I do not have. Could this potentially be the cause of my networking issues?
Note that when I open the list of network connexions it does include VirtualBox Host-Only adapter - so some installation has taken place, but possibly not all that's required.
