# Firewalld TUI Manager

A lightweight, user-friendly Terminal User Interface (TUI) for fast and safe management of `firewalld` directly from the console. Built specifically for system administrators working over SSH who want an intuitive workflow without wrestling with cryptic `firewall-cmd` syntax.

The tool provides full control over zones, ports, predefined system services, and source IP addresses right inside your terminal.

* 🎨 **Modern Terminal UI:** Seamless mouse and keyboard navigation powered by the [Textual](https://github.com/Textualize/textual) Python framework.

## 📋 Prerequisites

* Linux system running systemd with active `firewalld`
* Python 3.8+
