[CentOS] C6 gateway/firewall problem

[cliff here]

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.
