Easy IPTables is a web interface I developed to help users generate iptables rules without needing deep familiarity with the syntax. This project bridges the gap between networking novices and the often-intimidating firewall configurations.

Motivation

The idea for this project came from my own desire to better understand iptables syntax and firewall rules. As someone working in DevOps, I frequently encounter scenarios where network security and automation intersect. This project allowed me to improve my grasp of firewall rules while also honing my skills in:

  • Web application development
  • Backend logic for configuration generation
  • Deploying tools that simplify complex tasks

Features

  • User-friendly Web Interface: Designed to minimize the learning curve of writing iptables rules.
  • Dynamic Rule Generation: Users can select options for input/output chains, protocols, ports, and actions to generate custom rules instantly.
  • Preview and Copy Rules: See the rules formatted in real-time and easily copy them for deployment.

What I Learned

  1. Deepened understanding of iptables syntax:

    • I explored the nuances of writing effective firewall rules.
    • Learned how to translate common security requirements into specific rules.

  2. Improved DevOps practices:

    • Developed and deployed the app using modern CI/CD workflows.
    • Gained insight into creating developer-friendly tools that address practical challenges.

  3. Enhanced UX design for technical applications:

    • Balancing simplicity and functionality to cater to a broad range of users.
    • Leveraged feedback from peers to iterate and improve the interface.

Technologies Used

  • Frontend: Next.js (React)
  • Hosting: Vercel for streamlined deployment
  • Styling: TailwindCSS for a clean, user-focused interface

I’m proud of this project as it demonstrates my commitment to simplifying DevOps workflows and making technical tools accessible. If you have any feedback or suggestions, feel free to reach out!
