@craigmod that was what I ended up doing when I was with NTT, sticking their aterm rando router in between my wifi and paying them ¥500/month for the privilege and triple NATing my ipv4 network so that I could use ipv6. I remember I did it because they had all this marketing material telling me that the ipv4 network is super congested. In hindsight I don't know if I believe it now.

@liquidx + @maxfenton It's working!!

On the Deco. In the end, it was all because so-net hadn't "released" the hold on my NTT fiber connection. Anyway, returning the annoying Buffalo router and going full Deco be85 which makes me happy because the app is great and it looks good. Phew.

@craigmod @maxfenton congrats on persevering on this important mission! I'm sad to report I still haven't gotten ipv6 to work on NURO though in my case I'm nearly certain it's my routers fault and not the ISP.
