Mine officially supports it. However having configured the Prefix as they define and using SLAAC etc all my devices get their IPv6 addresses and can access the internet, I can even connect from outside the network so it all "works", but I have a bunch of issues. Neither of my ISPs defined DNS servers is available, I can't route one of the OpenDNS routers but the other works fine and then I have these periods where the entirity of IPv6 routing breaks for about a minute and then restores. Having done this with two different routers on completely different firmware now I can't help but think my official support from my ISP is garbage and they have major problems with it. I had to turn it off because it causes all sorts of problems.
