It's been a few weeks old, but still unanswered.
The problem is that as a wifi client only a single MAC address is
registered with the AP.
The systems behind the bridge have their own MAC addresses, which
the AP doesn't know.
You either need to setup your wifi with mesh support, run the
bridge on the AP instead of the client side, or run dirty tricks
with proxy ARP.
The best option would be to avoid bridging from wifi completely and
route a different net to your vm host or use a cable.
