[Evelyn Mitchell]

The ONT is a fairly stupid device, it translates between optical and
electric in order to pick up data for your address but is not firewalling.
If you have a router or firewall on your internal network that may be the
issue.

How are you testing that the 2605:b40:1516:a200:8433:8e2d:2bad:e833/64 is
reachable?

Are you using ping6 and traceroute6?

Is your router between the ONT and that server passing IPV6 traffic?

Is your firewall configured to pass IPV6 for that range?

You can test from "outside" with one of the online Looking glass servers.

I hope that helps. I haven't done much with IPV6 that is attempting to be
publicly routable.
