Thanks Rusty, this fixed the problem for me.
There's a second problem, outgoing network performance using a routed tap-interface is in the area of 20-30 kbit/second. I noticed this previously (which is why I wanted to test the latest version), in -rc2 what still worked was turning TSO/GSO etc. off, this seems to be without effect in -rc7. I'll have a look at this myself tommorrow unless someone beats me to it :)
