Do you perhaps need to run DHCPv6 on the link? I have the following:

So I basically let the link come up, re-apply the firewalling rules so
IPv4 traffic passes at least… then I run a script which re-starts
dhcp6c, wait a bit more for that to finish, then re-apply my firewall rules.
The `restart-dhcp6c` script is simple enough:

Possibly not the cleanest solution, but it works for me on Internode
here in Brisbane.
