The normal default route works correctly. The problem is just that I
cannot create an undefined default route (because one cannot know the
gateway while being disconnected).
Using a temporary gateway (10.10.10.1) or just 0 did not work when I
tried it, but now I am in the process of changing the way dial-on-demand
is handled and cannot test it. :(
Maybe our port of your old netstack is buggy. I hope all problems will
be gone with the new port.

Bye,
Waldemar
