* Fully test your configuration.
{{Admon/note | |When your iptables service starts or at boot time it has to load the rules from the file <code>/etc/sysconfig/iptables</code>.}}
* Make a backup of the file <code>/etc/sysconfig/iptables</code>
* Examine the file to see how rules are added.
* Enter in your 2 new rules created above.
