Firewall Configuration

What I Did:

​

• Firewall Installation and Configuration:
  Deployed and configured a software-based firewall (e.g., pfSense) within my home lab to serve as the network’s security barrier.

• Rule Creation:
  Designed and implemented custom firewall rules to block or allow specific IP addresses, ports, and protocols, ensuring the system adhered to best practices for traffic filtering.

• Testing and Validation:
  Used tools like Netcat to simulate network traffic and Wireshark to analyze packet data, verifying that the firewall rules were correctly applied and effective in blocking unauthorized traffic.

• Optimization:
  Fine-tuned the configuration to ensure optimal performance and security, documenting each step for repeatability and scalability.

​

Key Skills Demonstrated:

• Writing and managing firewall rules

• Traffic filtering and monitoring

• Hands-on experience with tools like pfSense, Netcat, and Wireshark

• Network security best practices

​

Outcome:
Successfully implemented and tested a functional firewall setup that effectively filtered and monitored traffic. This project reinforced my understanding of firewall configuration and network security, showcasing my ability to deploy and manage defensive technologies in a controlled environment.
