How do I stop the Orbi from advertising IPv6 in AP mode?
Passthrough normally means that the BGW320 is not routing. Which normally would require the Orbi to be set up as a router, not AP.
Can you clarify the setup?

This is just a link-local address, and shouldn't be related to your issue.

What ipv6 DNS resolver are you seeing when directly connected to the BGW320?
Do you get a response when you ping the ULA?

Nope: AP appears to be corrrect. The magic word in the GusTTavo post is: Firewalla

I was thinking that, but wanted some confirmation (since the Firewalla can be set up as a bridge).

Hm, and all IPv4 would come to the LAN from the ISP?

IPv4 is correct on both paths.

I just want clarity on the setup, with no need to guess.
