I guess Hetzner cloud has a weird IPv6 configuration.
Even using LXD to configure everything automatically, IPv6 is not working.
@angristan If its like Online, you can have only *ONE* MAC address. So all containers with others MAC than the main interface are dropped by the switch.
@benoit but what's the solution to this 🤔
@angristan None. Or map the main interface on all the containers. The main interface will need to have all the IPv6 address as aliases.
@angristan Or do NAT. I do NAT… Yes NAT for IPv6 😭
