LaraWall rule handler for Iptables. Receives data from the LaraWall instance via API and manages Linux netfilter firewall rules using the Iptables utility.

The handler is currently only tested on Linux distributions based on Debian!

This handler is fully functional, but because it is designed only as an example of handling rules from a LaraWall instance on a target server, it may have architectural flaws. For example, to import rules from API, it is preferable to use DTO.

The handler script needs to be run by a user with root privileges.

The system must have the iptables and ipset utilities installed.

For the firewall rules to work (restrict/allow access to server service ports) created by the handler, the default Iptables policy for the INPUT chain must be DROP.

$ composer create-project icemont/larawall-iptables-handler

After installation, set the handler settings in config/config.php

Note: if you installed the handler manually, you will need to copy the config/config.php file manually from the config/config.sample.php file.

Run the handler as root user and make sure there are no errors. Then add the script to the crontab task scheduler (as root):

* * * * * php /path-to-your-project/handler.php >> /dev/null 2>&1
