Thanks, that's helpful. Any suggestion for something explaining how all these tools and service fit together (or don't)?

  Not sure what exactly are you asking about. iptables/nftables is an interface for in-kernel packet filters. NetworkManager... well, manages your interfaces and connections. systemd-resolved/dnsmasq handle DNS. They mostly just do their own thing, with NM sometimes using the other ones as needed (for example, it will set forwarding rules up and run dnsmasq when you choose a "Shared to other computers" option in NM).

  For a complete but not up to date guide have a look at https://tldp.org/LDP/nag2/index.html https://tldp.org/LDP/nag2/index.html . And for more up-to-date but less complete guide https://wiki.archlinux.org/title/Network_configuration https://wiki.archlinux.org/title/Network_configuration .

    "Not up to date" is putting it mildly, idk if there is anything in nag2 that's still relevant these days; I get the feeling that it will just confuse more than inform at this point unless you already know the stuff and history.
