Check the User Manual for Virtual Box:
http://download.virtualbox.org/virtualbox/3.1.6/UserManual.pdf
Take a look at section 6.3:"VirtualBox.
A virtual machine with NAT enabled acts much like a real computer that
connects
to the Internet through a router. The “router”, in this case, is the
VirtualBox network-
ing engine, which maps traffic from and to the virtual machine
transparently. The
disadvantage of NAT mode is that, much like a private network behind a
router, the
virtual machine is invisible and unreachable from the outside internet;
you cannot run
a server this way unless you set up port forwarding (described below)."

I would suggest to manually set up your ip address and (or tune dhcp
server for VirtualHost).

Then should be easy to adjust your settings for iptables+squid.
