Well - actually VirtualBox does not supports port-forwarding natively
(unlike VMware and Qemu), but as a workaround, you can use
host-networking (as described in the VBox official docs, and my
VBOX-on-SUSE article) and then use iptables to forward ports.

While the article is for SUSErs, it might partially apply to Ubuntu as well.
