iptables rules do not load after a reboot

Issue

Why after setting and saving iptables firewall rules are they still not loaded after a reboot?

• After a reboot, the iptables rules are not loaded, and instead:

  • The firewall rules need to be re-defined, because the new rules were not saved/applied.

  • The iptables service must be restarted in order for the rules to load.
