Troubleshooting : when you add new rule and can’t start iptables service

Error : 

Job for iptables.service failed because the control process exited with error code. See “systemctl status iptables.service” and “journalctl –xe” for details.

when you add new rule and can’t start iptables service

Solution : First save iptables new rule

[root@XEN-SERVER~]# /sbin/service iptables save

Second : iptable service start

[root@XEN-SERVER~]# service iptables start

3rd : iptable service status

[root@XEN-SERVER~]# service iptables status

Remember it! When you add new rule then first save and then start iptables service. But many people without save and restart iptables service.
