Hey, a question: I also use ufw because I don't understand firewall rules properly. Is there a benefit for me, a desktop user who would like to set up a tiny home network and possibly setup an SSH server to connect from afar, to delve into iptables/nftables instead? I tried once, but couldn't understand how the rules work. Also, if there is a ground-up explanation of firewall rules, their uses and misuses, and illustrative examples, I'd love if people could share.
