How to log into a captive portal (public WiFi) when you have a system wide private DNS? (quokk.au)

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.

You can connect to your VPN already before changing DNS?

I was interested in having a VPN to my home network which just works over 443, so I can access everything in my home network even on public wifis in a safe way. Haven't managed to set it up yet though.

What do you use for travel router? Might be interesting as well.

I guess you use the DHCP-assigned DNS first, then change it to what you want after connecting. Tailscale is a great way to access your home network. Headscale is another one but I haven't used it.

I use a gl.inet router. They're like $30. They use OpenWRT.
