Ok, thanks a lot. The other VPN software I have used can also
transport layer2: openvpn has the bridge mode, tinc has the switch
mode. I was assuming wireguard had (or could aquire) this capability
as well. Are there reasons not to support this? I would like to have
your opinion.

Thank you for the advice, but then I think I will just hack something
with dnsmasq. The point of using mDNS was to avoid maintaining an
extra piece of software. The moment I setup an IGMP / MLP proxy, I
fail this goal, and at this point if I am going to set up something, I
would rather fall back to a DNS management tool.

Cheers,
