I`ve played around with Wireguard quite a bit. I`m definitely not a
total expert on it or IPv6 but do have IPv6 working on my home network.
During my initial foray into Wireguard, I found that for IPv4,
Wireguard doesn`t work on Layer 2 where the broadcasts that DHCP needs would
exist. IPv6 replaced broadcasts with multicast, which are still Layer 2 and
most of the autoconfiguration of IPv6 relies on it, including RA/RS
messages, SLAAC and DHCPv6.
So I *think* you can make a Wireguard tunnel with IPv4 on the
outside and 2 interfaces with IPv6 on the inside, you`ll just have to
assign the "inside" wgX addresses manually. E.g. fd77::1/64 and fd77::2/64.
You might need to add fe80:: addresses manually as well.
OpenVPN does work on Layer 2 if you use tap mode (Wireguard is
like OpenVPN in tun mode), and DHCPv4 will definitely cross it if you
have the tap junctioned into a bridge that a physical NIC is part of.
I got a Windows file share working over an Internet connection with
it once. I haven`t played with IPv6 over OpenVPN yet.
