CentOS7 and RHEL7 use Firewalld which is a bit complicated so I am going to show you how to disable it.

How to stop and disable firewalld

The following two commands will first disable firewalld and then stop it.

sudo systemctl mask firewalld
sudo systemctl stop firewalld

Thats it so you box now has NO firewalld running.. you should maybe think about iptables.
