/etc/sysconfig/ip6tables-config

The /etc/sysconfig/ip6tables-config file stores information used by the kernel to set up IPv6 packet filtering at boot time or whenever the ip6tables service is started.

Do not modify this file by hand unless familiar with how to construct ip6tables rules. Rules also can be created manually using the /sbin/ip6tables command. Once created, add the rules to the /etc/sysconfig/ip6tables file by typing the following command: 

service ip6tables save

Once this file exists, any firewall rules saved in it persists through a system reboot or a service restart.
