Indeed, I'm using Free (AS12322) at home, and while their homemade CPE
(Freebox v6) has a great admin panel with a lot of options, ipv6
firewalling is not available.

And as Mark Townsley noted (I guess you were talking about Free
right?), it uses 6rd. I've had some success scanning the 6rd prefixes
based on the IPv4 addresses, and low-byte addresses are quite valuable
results.
