Getting rid of firewalld and coming back to iptables
Here are the magic commands :
systemctl stop firewalld systemctl disable firewalld yum remove firewalld yum install iptables-services systemctl enable iptables.service systemctl enable ip6tables.service
Don't forget to configure SSH with system-config-firewall-tui. And after that :
systemctl start iptables.service systemctl start ip6tables.service
Replacing NetworkManager by network
Type these commands :
systemctl stop NetworkManager systemctl disable NetworkManager
And now, we can restart network :
service network restart
