Re: firewalld question

Same here, I didn't monkey with the firewall since the days of iptables, 
where I had my rules in a file that I'd load up in iptables. I would drop 
everything by default and only poke holes for things that I needed. Now we 
have zones and policies and stuff and I have to read an entire treatise on 
firewall just to add a simple drop rule. In fact I did add the rule, it 
just doesn't do anything. 

I'm intrigued by the fact that the GUI won't let me add the rule (but the 
command line does). Maybe there's something wrong with my rule and the GUI 
detects that, but then I would expect the command line to error out too.
