So, I'm trying to set up gluetun. I linked a Firefox container to it and apparently every check of DNS leaks shows that it's leaking. Cloudflare and quad9 are the servers, the same names that I've set to dot providers. So I am gathering from all of this that these leaks are to be expected? And non of the DNS servers show my real IP, always one of mullvad IPS.
Am I getting this right?
