'''FireHOL''' is a [[shell script]] designed as a wrapper for [[iptables]] written to ease the customization of the [[Linux kernel]]'s firewall [[netfilter]]. FireHOL is [[Free and open-source software|free software and open-source]], distributed under the terms of the [[GNU General Public License]].

FireHOL does not have [[graphical user interface]], but is configured through an easy to understand [[plain text]] configuration file. FireHOL first parses the configuration file and then sets the appropriate iptables rules to achieve the expected firewall behavior. It is a large, complex [[Bash (Unix shell)|BASH]] script file, depending on the iptables console tools rather than communicating with the kernel directly. Any Linux system with iptables, BASH, and the appropriate tools can run it.  Its main drawback is slower starting times, particularly on older systems. FireHOL's configuration files are fully functional BASH scripts in of themselves.
