 ### Behavior and Functionalities
 - **Allow ICC (Inter-Container Communication):** When `magicfw.firewall.allow_icc` is `true`, the container can communicate with other containers across **different Docker networks** (useful for applications like reverse proxies such as Traefik). If `false`, the container is isolated from other Docker networks (default Docker behavior).
-- **External Traffic:** When `magicfw.firewall.allow_external` is `true`, the container's network rules allow communication from external networks (useful when NAT is disabled).
+- **External Traffic:** When `magicfw.firewall.allow_external` is `true`, the container's network rules allow communication with external IPs.
 - **Automatic Rule Cleanup:** When a container is restarted, stopped, or removed, the corresponding firewall rules are automatically cleaned.
 - **Support for Published Ports:** Rules are auto-generated for any published ports, restricting incoming traffic to only the ports explicitly exposed via Docker.
 
-## Install
-To make the installation easy, I provide a package for Debian-based distros, follow the instructions here: [https://git.marcorealacci.me/marcorealacci/-/packages/debian/magicfw-docker](https://git.marcorealacci.me/marcorealacci/-/packages/debian/magicfw-docker)
-
-To install the script manually, the required dependencies are `python3` and the `docker` library available from PyPI (`pip3 install docker`).
