VirtualBox defaults to NAT for the virtual NIC
If you're trying to get in there from outside it can be a double NAT.
When I'm running something like an HTTP server in the guest,
I set the virtual NIC to Bridged mode
(which causes it to use the same NAT as the host,
if your host is your dev workstation and it's already on NAT).
