I'm currently running a pfSense router at home, which has limited IPv6 support. Does anyone have any suggestions for something with more extensive IPv6 support?

Specifically what I need is something which can handle my ISP only handing me a /64, and can smoothly handle prefix changes (update firewall rules etc).

Ideally also being able to register/update LAN clients on dyndns service so I don't need to install an update client locally on every device.
