=== How to use iptables instead of firewalld in OpenVZ7 ===
firewalld was introduced with CentOS 7 to manage iptables. If you prefer classic iptables management please follow these steps.
First, stop and mask the firewalld service:
# systemctl stop firewalld
# systemctl 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
