I've done something similar for about three years now on a pc acting as a router for our residential internet access using user-mode linux, and it's worked quiet well for me so far. Your mileage may vary of course. I configure the interfaces on the physical box statically, and bridge the guest doing all the heavy lifting using tap devices to the host's physical interfaces. I also automatically start the uml guest during the host's boot sequence. Doing it using a virtualbox guest shouldn't be all that different. The only thing that I need to take care about so far is to remember to access the remaining machines on the network via IP address when I take the guest down for some reason. Doing that also cuts off internet access to the outside world from my LAN. Hope that helps you in some way.
