Hi all

I'm using DNS over TLS with Quad9 as my DNS provider.
This works great in most circumstances, but when I want to connect to a public wifi, like at school or in the library, it's not possible to open the Captive portal page, and I can't use the network.

Is there some way to easily make this work? Maybe exclude these networks from private DNS?
Or a way to easily switch between network configurations?

I'm using systemd resolved, but configured with a private dns via my NixOs configuration.

True, I just found it convenient to block ads and trackers on a system level.

If you are using something like nextDNS it's very easy to block ads and trackers everywhere, and even block social media or adult websites and such.

So using DNS over TLS is not necessarily about hiding my internet traffic, but more also to limit unnecessary content. I suppose the same can be done with a combination of browser extensions. But using the private DNS made sense to me.
