Firewall Rule Management Script

This repository contains a Bash script designed to facilitate the management of iptables firewall rules. It provides a user-friendly command-line interface for listing, adding, and deleting iptables rules.

Features

• List Current Rules: Displays all current iptables rules with enhanced formatting for better readability.
• Add New Rule: Allows the user to add a new rule to the iptables, with inputs for chain, protocol, port, and action.
• Delete Rule: Enables the user to delete a specific rule by specifying the chain and rule number.

Requirements

• iptables installed on your system.
• Bash shell environment.

Usage

To use the script, follow these steps:

1. Clone the repository to your local machine:

   git clone git@github.com:vm32/Firewall-Rule-Management-Script.git
   chmod +x firewall_rules.sh
   sudo ./firewall_rules.sh

Compatible Linux Distributions

The iptables management script is compatible with a wide range of Linux distributions that support iptables and have a Bash shell environment. Below is a list of some popular distributions where the script should work without issues:

• Ubuntu: All recent and LTS (Long Term Support) versions.
• Debian: Stable, Testing, and Unstable branches.
• Fedora: Including current and some previous versions.
• CentOS: Versions 6, 7, and 8 (CentOS 8 has shifted to using nftables by default but iptables are still supported).
• Red Hat Enterprise Linux (RHEL): Versions 6, 7, and 8 (Similar to CentOS, RHEL 8 uses nftables by default but supports iptables).
• Arch Linux: Rolling release model ensures up-to-date iptables and Bash versions.
• Manjaro: Based on Arch Linux, hence fully compatible.
• openSUSE Leap and Tumbleweed: Both the regular release and rolling release versions.
• Mint: Based on Ubuntu and Debian, so it's fully compatible.
• Slackware: One of the oldest distributions that still maintain iptables and Bash in its environment.

Prerequisites

Before running the script, ensure that iptables is installed and that you have sudo or root access to manage firewall rules. Some distributions may use nftables as a default firewall management tool. In such cases, you might need to install iptables or use its compatibility layer.

Note

This list includes distributions that are known to support iptables and Bash, but it's not exhaustive. The script may work on other distributions that meet these requirements. Always ensure that your system is up-to-date and has the necessary permissions to modify iptables rules.
