Does anyone have a iptables guide / tutorial for absolute fucking retarded monkey like me?
I've been struggling for days with firewalls. ufw doesn't work, nftables doesn't work, and even iptables is just twiddling thumbs when I'm trying to set up rules (rules don't show up when I insert them).
Also where the fuck does debian 12 get its default iptables from? /etc/iptables does not exist, yet there's a standard set of tables when my VPS launches and another set that pops up as soon as Incus starts the containers.

Been driving me mad for days now.
