As of Fedora 18, the iptables service has been replaced by firewalld. For those that prefer managing static firewall rules with iptables, follow these steps to revert back to iptables.
You will need to have a Fedora 21, 22, or 23 cloud server provisioned and root permissions.
Using IPTables instead of firewalld
Disable firewalld and stop the service with the following commands:
systemctl disable firewalld
systemctl stop firewalld
Now install the iptables-services package:
dnf install iptables-services -y
Enable iptables and start the service:
systemctl start iptables
systemctl enable iptables
Check to make sure iptables is now running:
systemctl status iptables
Your output should look like this:
You’re finished! Now start adding your rules to the /etc/sysconfig/iptables file.
