[SOLVED] Using Mullvad DNS

[used1d]

Anyone know how to use Mullvad DNS for pve? I put dns.mullvad.net in Search Domain, and 194.242.2.2 for DNS1. Yet, I am unable to connect to any repos for updating after doing that. Any help is appreciated!

Please note the following sentence on their product page:

These IPs can only be used with DNS resolvers that support DoH or DoT, not with DNS over UDP/53 or TCP/53.

All nameservers in /etc/resolv.conf must support "plain-old" DNS via port 53.

You can theoretically use them directly via systemd-resolved: https://mullvad.net/en/help/dns-over-https-and-dns-over-tls#linux
But Proxmox VE does not use systemd-resolved; so any setup (and problems/fallout thereof) are not really supported.

I'd recommend to deploy and use a separate server as DNS in your network, if you really want to use Mullvads DNS servers.
