Hi, Rick.
Although I've already configured network access for virtual machines
using VirtualBox capabilities to brige host network interface, it
seems than VLAN-approach is also possible. A fast google reveals many
results on VLAN configuration (for example, I've found this link:
http://www.stg.net/vlanbridge ).
