NH20A router ignoring configured DNS forwarding — confirmed with AdGuard test
I've configured my NH20A router (logged in as admin) with specific IPv4 and IPv6 DNS addresses from AdGuard. After rebooting both the router and my laptop, I confirmed that the laptop receives the ro...
Has anyone applied specific DNS servers to the NH20A router, and how do you know if they're working?
It's been 2 weeks. Doesn't anyone use the NH20A, or maybe no one has wanted to replace the Telus DNS servers?

For the NH20A, custom DNS settings in the admin interface are limited, and in many cases the router will still default to TELUS DNS on the backend. At this time, the device does not fully support enforcing alternate upstream DNS resolvers, even when manually entered so the behaviour you’re seeing is expected with this hardware. If you need full control over DNS (including AdGuard, Pi-hole, Cloudflare, etc.), the best workaround is to place your own router or firewall behind the TELUS hardware and manage DNS there. Many customers use bridge mode or a secondary router setup for this purpose.
Thanks. It's stunning that a modern router provides a place to enter your custom DNS servers and then ignores them! I haven't run in to that in the last 30 years of doing networking. It's now something I will inquire about with a new supplier when I decide to leave Telus behind.
