Hello, I bought this router almost a month ago and I'm still amazed at everything it can do.
Yesterday I decided to reset it and start my configuration from scratch.
I noticed that when connecting via the guest network on the wireless, it is not possible to resolve DNS via IPv6 if AdGuard is enabled.
Enable AdGuard Home: ON
AdGuard Home Handle Client Requests: ON
IPv6 Mode: Native (I don't know if this has any influence, since the guest will always use NAT6)
So, if you try something like:
nslookup google.com 192.168.9.1
It works perfectly.
However, if you try something like:
nslookup google.com fd8b:1234::1
It will time out.
I'm not sure if this was really the expected behavior.
PS: Remember to adjust the network addresses to their respective values.
PS2: It would be great if it were possible to adjust the ULA IPv6 network prefix. I saw that it is possible to adjust it through the LUCI interface, but changing it there, there are places that are not changed together, such as the glipv6 file.
Right now I have a lot of changes, but when I found the bug, I reset the router and reproduced with the minimum possible.
You can ping it, but you can't use to do a nslookup.
Also I didn't make my self very clear. My router is dialing a pppoe connection, I'm not using it as a repeater, not sure if that matters.
Let me know if you can reproduce it, if not, I can reset the router again do the changes and export a config. Is that ok for you?
But the problem is not the ping, it is the DNS resolution that fails on IPv6 using the guest network.

In the first test, I was connected to the wireless guest network.
In the second test, I switched to the main wireless network (cable also works).
In other words, the DNS server is working, but there must be some firewall rule that is preventing it. I didn't get to look into it much, because it was already late and I needed to restore the router so that people wouldn't kill me in the morning when there was no internet
Seems some problem is in the DNS service of your router?
Reset to firmware, only enable ADG (default configuration) + IPv6 Native + Guest WiFi, see if the nslookup works? or what ADG configure?
When I received the email this part is not there, so I did a full reset and video of 10 minutes. Ops!
(Hint: always check if the post has been updated first)
Anyway, I will send you a PM with the link for the video and the router config exported. It may help.
