Bridging looks to be a world of pain so I'm next going to look at NAT forwarding through the Ubuntu host - will report back.

This is starting to take shape nicely. VM now autostarting on Ubuntu with persistent firewall rules port forwarding SSH and HTTP,  and X sessions tunneling nicely back to a Windows desktop.
