TCP/IP Networking - Network Configuration and Service Implementation

This assignment solution details the configuration of a TCP/IP network, encompassing the setup of PCs, servers, and routers. It includes step-by-step instructions for configuring network interfaces, implementing IP packet forwarding, and verifying connectivity through ping and traceroute commands. The solution further explores the configuration of essential network services, such as DHCP for dynamic IP address allocation, a web server for hosting content, DNS for domain name resolution, and a firewall for network security. The document provides configuration details, including the routing tables, and demonstrates the functionality of each component within the network. The assignment is designed to provide practical experience in network setup and service implementation.
