Hi i'm trying to spin up VMs on public ipv6 address's.
When I enable net.ipv6.conf.all.forwarding = 1
on the host it seems to kill the ipv6 connectivity
root@li166-218:~# ip -6 route show dev eth0

connect: Network is unreachable
when net.ipv6.conf.all.forwarding = 1
I can ping the host from the guest vm. Hoever the host no longer has public ipv6 connectivity.
