Ya, i agonized over accepting firewalld.
I'm a smalltime manager who wears many hats and doesn't have alot of
time to practice sysadmin skills.
It took me about 5 years to get confident with iptables and go from
fresh install to company firewall in one sitting.
Now that I've adopted firewalld which has a wider variety of
command/rule statements, I am constantly hitting "man firewall-cmd"
and cannot competently recall iptables in any comprehensible way; it's
like mixing Japanese and English whenever I try to communicate with a
centos box firewall, heh.
