+[[https://www.digitalocean.com/community/tutorials/iptables-essentials-common-firewall-rules-and-commands|digitalocean.com]]
+For this configuration file you need to truncate both __//sudo//__ and __//iptables//__ from the start of the command.\\
+To apply these new rules you need to perform one of the following tasks:
+  * Reload your network stack: <code bash>iptables -F; service networking restart</code>
+  * Restore the config directly: <code bash>iptables -F; iptables-restore < /etc/iptables.up.rules</code>
