virtual mac abuse on hetzner due to network bridging on proxmox ...
I have several VMs. all of them have 2 network card.
one of them is NAT'ed to the ipv4 interface on the host. no problems here.
the other one is bridged to the same interface, and running only ipv6.
I was running the vm with one address each, from the /64 block.
then this happens. and I'm not sure where to start fixing.
I even tried to play around with tunnelbroker.net, but somehow I can't configure it for multiple hosts. only one VM would work and the other would lose ipv6.
the original plan was every server would have its own ipv6 address.
