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 ). -- Hiisi. Registered Linux User #487982.
