Where is iptables config stored

With the new Responsive Firewall it seems that there is no /etc/sysconfig/iptables.
I would like to add a few rules to iptables and cannot find where to add them.
I take it that the new firewall programmatically add their rules.
How can I add mine and make sure they are there after a reboot?

Asterisk 11.21.0
Installed from Distro

You add rules through the GUI. There is no ability to manually add specific entries.

What do you want to add, exactly?

Sorry for the late response, some reason I’m not getting the notifications.
In the past I have blocked out most of Europe, Africa and China using ipset.
