I don't understand anything; what is in debian 12 : iptables, iptables-persistent and netfilter-persistent - it's all installed
Debian does not install these packages by default.
Either you manually installed them or as a dependency of another package, you can find reverse dependencies with e.g.
https://reintech.io/blog/configuring-ip ... -debian-12\
"Debian 12 typically comes with IPTables installed by default."
"After configuring your rules, you need to save them to ensure they persist after a reboot. On Debian 12, you can save your IPTables rules with the following command:
sudo netfilter-persistent save
To reload your rules, you can use:
sudo netfilter-persistent reload"
So netfilter-persistent is a utility for working with rules. It remains to find out what iptables-persistent is
iiptables-persistent is boot-time loader for netfilter rules, iptables plugin
netfilter-persistent is a loader for netfilter configuration using a plugin-based architecture. https://packages.debian.org/en/sid/iptables-persistent
This package contains the iptables and ip6tables plugins.
It turns out that iptables-persistent contains iptables and netfiltelter-persistent
