Ok, I see. Progress was the other way round.

Yes it does fix my problem.
So, if we consistently use "dev" instead of "vif" the we'll run into troubles
in vif-route and vif-nat scripts sooner ot later if we don't fix these as
well, don't we?
I changed "vif" to "dev" in both, though I haven't testet the nat one for lack
of testing environment.
