That could be due to what you're pinging.
I can ping the same addess from the pfSense CLI, so should it not also work in the Gateway Monitoring.
-
You'd think so. Did you enter the address for the gateway? Or just leave the box blank. It will default to the gateway address, so you don't have to enter anything. You could try putting some working GUA, that you can ping, in that box.

Gateway is set to dynamic and cannot be changed.

Sorry, I do not know how to do that.

First, go to a command prompt in pfSense and traceroute6 go Google:
traceroute6 google.com
traceroute6 to google.com (2607:f8b0:400b:807::200e) from 2607:f798:804:90:3899:8d05:91dc:56e3, 64 hops max, 28 byte packets

What happens if you disable gateway monitoring for IPv6?

Well, you obviously have a problem with how the monitor is configured,but I don't know how at the moment. Regardless, don't worry about it, as for most users it's not used. All I can say is use the default, if it works or plug in an address you know works.
Anyway, you appear to be up & running with IPv6.

I think you're correct. Would it help removing and adding it back in?
Thanks again for all your time and putting up with me.

As I mentioned, you don't have to put anything in, provided the gateway can be pinged. It's only when it doesn't that you have to provide some other address.
-
@JKnott said in prefix length should be 64:
That could be due to what you're pinging. While you can ping a link local address, your ISP might not have configured it to respond.
He was clearly (trying) pinging googles dns server. Maybe you should enable pictures for the forum to see them (if you are able).

Sorry, but can you please explain what you mean by this?

What pictures are you talking about? I already included examples of me doing it.

Given the pictures are already there, what would it accomplish to provide more? I often post pictures when I think it would help.
