That is my question, *how* to stop it from running?

I could very simply do that by renaming scripts in init based systems,
here I don't have clue.

I have firestarter running, however that also doesn't provide a method
to close the ports.

I could do that in firewall configuration in Fedora, here there is
just no option to do that here in firestarter.
