Wireguard ipv6 over ipv4-tunnel

[leifnel]

I have a wireguard vpn running over ipv4 between a site with ipv6-connectivity and a /64 to a site without ipv6

Can I assign some of the ipv6-adresses to the ipv4-only site and route over the vpn?

Is this possible?
Any recipies on how out there?

Fundamentally, yes. But you cannot subnet a /64. You need another /64 for the IPv4 only site. I run this in production.

You could subnet the /64 for link networks and such, but you can not have anything other than a /64 for a lan network.
