It is possible to go back to a more classic iptables setup. 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

or

/usr/libexec/iptables/iptables.init save

그 외 자주 쓰는 명령어: 

iptables -F //초기화 

iptables -I INPUT -p tcp -m tcp --dport 22 -j ACCEPT // 22번 포트 오픈 

iptables -D INPUT -p tcp -m tcp --dport 22 -j ACCETP // 삭제 

 

 

 firewall-cmd --zone=public --add-port=80/tcp --permanent

 firewall-cmd --reload
