when changing the dns to NextDns, I am no longer able to browse the router.asus.com. I am not sure if I understand why, it works fine with any standard DNS without me adding it manually.
what can be the issue? why does the domain router.asus.com does not work? and if I need to add the entry manually, how can I add it at NextDns?
Let me try to explain a little more what I am confused with
I was using the Asus router with my previous dns provider, and the router.asus.com was resolving to the correct IP of the router, when I switched to nextdns, it does not work anymore.. it might seems obvious since the entry probably does not exist on the nextdns servers, but what get's me confused is that it did not existed in my previous dns provider as well
So, I guess what makes me really confused is, how it was possible to be working before with my previous dns provider? and if we know the answer, maybe I can replicate it to NextDNS?
The other question I have is, it is not possible to create a manual DNS entry and NextDNS?
Easy fix is go to settings > rewrites. Add router.asus.com and for the target put in your Asus's router ip address. I use opnsense and use unbound dns on my router for lots of local services. In the cli client I have a few customizations the ones I had to do that to let my router handle resolution for local domains was forwader mydomain.com=10.0.1.1:5352 (this is your router's IP) The port 5352 is what I changed my unbound service to answer on. So basically nextdns cli sends the majority of my name requests to the nextdns service, but then I sitll can get my local name resolution I need. I use a different IP for my web services inside than outside.
So you could put in forwarder router.asus.com=X.X.X.X which would be your router's IP address.
Before operating an ASUS router , a user has to register the product in an ASUS account. Without registering your product in an ASUS account, you cannot operate the router in a network. After you log in to the ASUS account, a user becomes eligible to receive various product promotions from ASUS. Go to the official website of ASUS and register your product there before performing the router.asus.com setup process.
