Just make sure that  the default iptables policy is DROP!
Then open specified ports that have services.

Anyway, Google "fedora firewalld tutorial". Some results:

Firewalld is for beginer, i think.
when complex rule required, rich language just dump your iptable cmd to the system
then why not go straight to iptables

Anyway, take your time in learning Linux. DO NOT bet on Linux for a better career. It's not there yet!
