CentOS 7 | Disable and enable the firewall

"Hey Tom, I am just doing this tutorial article about setting up my Apache server but damn I did everything twice and I still can't access my server from outside but the service is working?!"

Every now and then I get these questions from people who just installed their CentOS 7 server and now they are trying to setup their whatever network service.

The pain my friends is the firewall on the CentOS 7 machine that comes installed by default.

There are two solutions for this, both with advantages and disadvantages.
