Okay. Back to the drawing board. This re-use of tap0 is a libvirt quick of domxml-to-native, as documented https://libvirt.org/drvbhyve.html .

Looking at my ifconfig output I see:

bridge10:
  member vnet0
  member vlan10

bridge11:
  member vnet1
  member vlan11

Now, if I have two interfaces as described, traffic will not flow through either of these. If I remove one, and have a single interface on the bhyve guest traffic flows.

Ideas? 

(Again, I'm offlist so please include me in replies)
