On a similar note, Is there any reason to use Firewalld over IPTables? I'm incredibly new to Linux administration, and would like to your guys' opinions on it. Many thanks, Joel.
My first impression was that firewalld and NetworkManager had a more desktop oriented/plug-n-play type feel compared to traditional tools like network and iptables so I chose to stick with the latter on my servers (manual IP4/IP6 configuration and a handful of services, some open to the public internet while others open only to certain sources). For a laptop or desktop (which probably uses DHCP and has few, if any, publicly accessible services) I'd probably stick with the former. I have no idea how well tools like fail2ban or logwatch integrate with firewalld, but if they work as well or better than iptables that would be great. Warren is correct that the firewall-cmd interface is probably more intuitive for most folks (especially those not familiar with managing iptables).
