This project provides a network diagram solution for Fractal Apps, a software development startup. The solution proposes a standardized LAN for data communication between three offices, a WAN for effective communication among employees, and a VPN to enhance data privacy and security. The document details the components of the network, including LAN (using coaxial and CAT 6 cables and network switches), WAN (utilizing wireless routers and switches), and VPN (employing a firewall-linked VPN and MX60 router). The network diagram illustrates the interconnection of the headquarters, sales office, and development house using LAN and WAN networks, with a firewall for data protection. The project aims to facilitate easy communication and manage data transmission issues within the company.
