This seems promising. I will test it.

Thanks

But after investigating logs kea was receiving dhcp6 request over wifi using the ethernet adapter mac address. How is this possible? Is it possible the MAC address in DHCP does not match L2 MAC address? I did not sniff the request, yet. I decided to switch back to DUID assignment since this problem is worse than the previous.
