I have Quantum Fiber in Colorado and enabled IPv6 on the old CenturyLink C4000XG modem following these directions: https://www.centurylink.com/home/help/internet/modems-and-ro...

That uses 6rd which is typically slow (since it basically proxies through an ipv4->6 bridge), and in my case it worked on their provided router but not with opnsense.
