There is an inverse way as well, in iptables there are some WantedBy=
lines, follow them and they may lead you to the right source.
Unfortunately another way of start scripts invocation are through dbus.
You may also install graphviz and try
systemctl dot|dot -Tsvg > systemd.svg
but at my system the output look too complicated to find something.

You're right, sorry for the misclick.

I don't really understand what you want to achieve, but this
solution I have found as the most suitable - you will still have default
iptables running and accepting what is very close to not running them,
and when you want to restrict network rules, you just switch to another
ruleset instead of starting.
