There is something I'm missing from my virtual box setup but I cannot
understand what.
I've a linux box running a virtual box 3.8 on top of which FreeBSD is
running. The networking is NAT, FreeBSD is running in dhcp mode.
The 192.168.200.1 is the vbox interface, 192.168.200.101 is the
address assigned by the dhcp server.
The linux box has ip forwarding enabled.
However, the FreeBSD machine is unable to get any data going outside
(please note: the linux box network is on another private address
class).
Any idea of what silly detail I'm missing here?

Thanks,
Luca
