Firehol - ArchWiki

# Firehol

FireHOL is a language (and a program to run it) to build secure, stateful firewalls from easy to understand, human-readable configuration files. The configuration stays readable even for very complex setups. In the background it interfaces with iptables (IPv4/IPv6).

## Installation

Install fireholAUR or firehol-gitAUR.

## Configuration

The configuration file is `/etc/firehol/firehol.conf`.

A good way to start learning its scripting declarations is by copying an Firehol example configuration.

The configuration file is bash file and has 3 parts:

- helper
- interface
- router

## Try, Run and Enable

You can test the configuration file's correctness by issuing:

    # firehol try

or

    # firehol nofast try

If the configuration is working, start/enable the `firehol.service`.

Tip:

- The package also includes FireQOS, a helper for Advanced traffic control. It is packaged with its own `fireqos.service`.
- The netdata (or netdata-gitAUR) application for traffic monitoring, created by the same project authors, also is available. See Netdata for more information.
