= How to edit iptables rules

In this how-to, we will illustrate three ways of editing iptables rules, via:

* Command line interface (CLI): `iptables` and system configuration file `/etc/sysconfig/iptables`.
* Text-based interfaces (TUI): `setup` or `system-config-firewall-tui`
* Graphical user interface(GUI): `system-config-firewall`

NOTE: This how-to illustrates editing existing iptables rules, not the
initial creation of rules chains.
