Also to note, if you edit your /etc/sysconfig/iptables file manually there is a line in /etc/init.d./iptables at line number 300 that will save on service iptables restart; meaning if you run that command the buffer will save over the file and basically revert any changes you just made to the file.
Well, it's line 300 on CentOS 5, not on CentOS 6.
If you mean that having "IPTABLES_SAVE_ON_STOP=yes" set means it saves on restart, well yes. But that's not the default, so you've changed your setup to do that as far as I'm aware.
