Red Hat Firewall
Summary: How to configure the Red Hat Firewall.
Date: Around 2014
Refactor: 29 March 2025: Checked links and formatting.
There are two ways to modify the firewall on a Red Hat box, and these two are not compatible with each other. So keep in mind that if you use one, you have to stick with that. So again, there are two options, the tooling (mostly done with the graphical tool) and editing the config manually. If you make a change in the config file manually, it won't be picked up by the tool. So, if you're working with multiple people on a server, make sure to document or talk about these things! In this page I'll discuss the graphical tool here versus manually modifying the config files. If you work with the tooling you can also use the iptables command. For more information about that look here.
