(+)/etc/sysconfig/ip6tables-config
The content saved in this file is used to give the kernel the Ip6tables service to start or set IPV6 filtering rules.

Rules can be created by using the/sbin/ip6tables command and save the rule to the/etc/sysconfig/ip6tables file, which saves the rule using this command: Service Ip6tables Save
Once all the rules are saved to the/etc/sysconfig/ip6tables file, the system IPV6 Firewall is set by reading the rules in this file when the Ip6tables service starts or when the system starts.
(/etc/sysconfig/iptables-config)
The content saved in this file is used to give the kernel the Iptables service to start or set IPV4 filtering rules. Do not edit the contents of this file directly unless you are very familiar with the structure and rules of iptables. Rules can be created by using the/sbin/iptables command and save the rule to the/etc/sysconfig/iptables file, which saves the rule using this command: Service iptables save
