1.2 iptables-services Package Includes Support for /etc/sysctl.d

The init scripts for the iptables and ip6tables services includes support for configuration files that are located in the /etc/sysctl.d directory, as well as /etc/sysctl.conf. This enhancement ensures that any user-provided files in /etc/sysctl.d are also correctly accounted for when the iptables service restarts.
