Travis, welcome to the Fidonet IPv6 club!
Thank you very much! It seems that OPNsense has a few minor issues with IPv6 causing it to lose IPv6 connectivity intermittently. At least now with my kids having Disney+ on our Fire Stick (which defaults to IPv6 when available) I notice pretty quickly when it stops working and can usually get it back up before I lose my current /64 and have to redo all my DNS records again.
Supposedly the latest update for IPv6 has some fixes for this issue so fingers crossed it won't be a problem anymore once I have the chance to upgrade.
Also, apologies for the alias on my other message, the settings for this echo should be fixed now.
