I'll try that, thanks.

Oh, of course.
I tried a dummy device, no change in behavior.  I tried removing the "direct;",
no change in behavior.

Unfortunately this machine only has one "real" interface (and it's a VPS so even
that is not really real), so I'll probably just lock myself out if I try to put
that into a VRF.

Kind regards,
Ralf
