In this video, I’ll walk you through the complete setup of a network simulation environment using Graphical Network Simulator-3 (GNS3). We’ll cover how to:

-Install and configure a custom Cisco IOS router within GNS3 to serve as the backbone of our network.

-Integrate VMware Kali Linux as a virtual machine, allowing us to perform network analysis and simulate client interactions.

-Add a default PC within GNS3 to act as a typical network device or « victim » machine.
-Configure subnetting on the Cisco router to assign IP addresses to connected devices, ensuring seamless communication across the network.

-Connect all devices through a virtual switch, placing them on the same network segment to facilitate packet transmission.

Throughout the setup, we’ll focus on:

-Simulating network traffic using protocols like ICMP (ping) to test connectivity between devices.

-Analyzing network packets to understand how data flows through the network.

-Monitoring for anomalies in traffic to gain insights into network security and performance.

This comprehensive tutorial is designed for beginners and intermediate users interested in networking, cybersecurity, or systems administration. By the end of the video, you’ll have a fully functional GNS3 lab environment where you can:

1. Practic networking concepts and configurations in a risk-free setting.
2. Experiment with different network topologies and device interactions.
3. Enhance your understanding of network protocols and security.
