I'm not sure how to do it with nmcli, but I did it via the network icon on the desktop, with some edits of configuration files in order to use knot-resolver as a caching dns server with a dns provider other than my ISP. It really improves the speed of page loading on sites that I visit often. Here are my procedure notes. I don't remember the procedure because it was months ago, so there might be something missing that I fixed and didn't add to the notes. Bad dog! Bad, bad, dog! You should be able to put all those steps in a script that runs at startup. """ I was able to get knot-resolver to act as caching dns server with the modem serving as its source. For the connection, I set the dns lookup to 127.0.0.1 and told NetworkManager to only get the dhcp address, no dns address. In the connection icon in the gui. I told NetworkManager in its configuration file, /etc/NetworkManager/conf.d/config to disable dns management, to turn off resolver, to not touch /etc/hosts. I edited the /etc/hosts file, commented everything already there and left only the line with 127.0.0.1. I edited the knot-resolver configuration file, and added the procedures entry to the tables. I turned off the dnssec lookup. I then used a stub entry to tell it to only do lookups. I have to do a systemctl restart kresd@01 after each reboot to get the dns lookups working, but it saves the current table on shutdown, and restores it on boot. So, it is working properly.
