Umm … no. Wireguard doesn't do ARP because it already knows where to send packets. It also doesn't dynamic assign IP addresses because you already need a way to exchange information before setting up the WG link (i.e. the public keys). It's trivial to also exchange IP addresses when you do that. I'll leave the question of whether/how to route multicast packets to somebody more knowledgeable. -- -- Matthias Urlichs
