In a previous question I asked how to configure m0n0wall in a VM. Now I would like to set a network addaptor in my machine to be used for the guest VM only, that is, not allow any traffic from the host machine to pass through. I have so far been unable to find a way of doing this. I am using VBox 4.0.0.
I have two physical network cards, one which I would like the host to use and one for the guest.
I've tried disabling the two boxes in red (which then disabled the boxes in green) and left the "VirtualBox Bridged Networking Driver" ticked, but this hasn't worked (or maybe I was expecting this to work more easily than I had hoped).
The idea is to have the VM running as a gateway on the host machine.
