This is what I originally expected - although I was supprised when I
could not get internet connectivity from the guest - I originally
thought it was routing issues, but iptables was all I needed :) (oh, and
the refresh on how iptables works etc etc - damn getting used to gui's
for most things!)

As a way of getting it to work I was very happy binding it to dummy0 -
but now I have a better understanding, bye bye dummy0 :)

Thanks again
