[clue] Firewall tool recommendation.

[David L. Anselmi]

What do you use to manage your firewalls? (By which I mean any networking rules on any of your 
(Linux) machines.)

I've been doing my firewalling in my network devices rather than hosts but I guess it's time to join 
the 21st century where everything has a firewall.

So I'm looking for something that makes simple things easy. Making complicated things possible would 
be nice too.

On one machine I'm using firewalld because that's what was there. Not sure that I like it.

So if you have a favorite, what is it?
