Need to set different DNS configurations for home and work

After a lot of testing and trial and error, I think I found a working solution.

I decided to remove all the configurations I had done, re-read the docs, and started from scratch.

systemd-resolved now has the following global configuration (at /etc/systemd/resolved.conf.d/)

[Resolve]
DNS=...
DNSOverTLS=opportunistic
Domains=~.

NetworkManager has the following global config:

[main]
dns=systemd-resolved

I removed all NetworkManager dispatcher scripts. And that’s it! The good old KISS principle strikes again :wink:

I believe the key points were: providing a global DNS config, setting DNSOverTLS to opportunistic, and setting the default Domains to ~.

With this, DNS queries with the work domain are being directed to work DNS, and all others to NextDNS :raised_hands: (regardless if am physically at home or work)

I don’t claim this is the proper way to do it, but I am glad this is (finally!) working :sweat_smile: I’ll mark this as the solution, but if anyone has any improvement to contribute, I will be more than happy to include it here.

Thanks to all that helped!
