With RHEL 7/centos 7, FIREWALLD is introduced to manage iptables. IMHO, FIREWALLD is more suited for workstations than for server environments.

It's possible to go, and a more classic iptables setup. First, stop and mask the FIREWALLD service:

systemctl stop firewalldsystemctl mask firewalld

Then, install the Iptables-services package:

yum install iptables-services

Enable the service at Boot-time:

systemctl enable iptables

Managing the Service

systemctl [stop|start|restart] iptables

Saving your firewall rules can be done as follows:

service iptables save


/usr/libexec/iptables/iptables.init save
