Some of our clients reported us they were unable to save iptables rules on their servers. That's why. we're writing the tutorial to fix their issue.
Output (when they tried to save custom iptables rules):
[root@server1]# service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables: /etc/init.d/iptables: line 268: restorecon: command not found [FAILED]
If you face the same issue, simply run the following command:
yum install policycoreutils -y
The above installation will solve the problem with the iptables-save option. :)
