Hmm, so the dhcp over ipsec doesn't seem to be working, has that code made it 
into 2.1.4 completely?

choosing use an existing adaptor and current address with autoconfiguration 
disabled works fine, tunnel comes up and I can access machines at the other 
end, any choices using dhcp over ipsec fail as below.
