I have just been lying in the bath and realised I perhaps didn't explain it clearly enough. You only have 1 ip address from VM which has to be shared between all the devices on your network which is why the router has one address for it's wan port and then dished out different local and non-routable addresses for the devices connected to it. The problem with double nating (network address translation) is that all the traffic for everything connected to the last router in the chain gets bundled under one address (in your case 192.168.0.2 from shub) and then the next router bundles it under another address (wan ip from VM in your case) and you have to hope that when your get the response back off the internet that the data/packets can find their way back to the originating device. Most of the time you wouldn't have problem and everything would work perfectly fine but when it comes to the shub, you are just asking for trouble.
