Or use "service iptables save". On systems where I use raw iptables, I 
set the thing up with the command line tools and then use that command 
to snapshot the running firewall to the sysconfig file.

I'm using firewalld now, but I still inspect the resulting iptables to 
see what it does. You can do this with "iptables-save > 
/tmp/iptables.txt". (That's the command that the initscript uses under 
the hood to save the boot-time sysconfig file.)
