The problem I am having continues. My ISP does not provide a router, just the ONT.

And we'll try and help you, but as I said, saying it stops working after twenty minutes doesn't tell use anything... apart from it not working apparently.
Start by giving us some more information I assume you are using dhcp6, what do the logs say? Have a look at the general logs and add a filter for dhcp6c. As I said, add a gateway monitor but use a GUA address as the Monitor IP, see if that also fails. Have you tried a traceroute -6 to one of the googles servers?
When it fails are you losing the GUA addresses on your LAN also?

What I mean by failing is that after OpnSense is rebooted "ping6 google.com" works. After 4 minutes, it no longer works. This is directly from OpnSense (not some workstation on my LAN). My ISP configuration is ISP -> ONT -> OpnSense. Same result regardless of the setting "Request only an IPv6 prefix". I read someone elses post (can't recall where at the moment and I don't have the URL handy) that they were having IPv6 reliability issues and they moved back to 20.1 and their issues were resolved. I'll be trying the same thing, but will not be able to for a few days.
