Virtual Private Network Design for Sheffield Hallam University Campus

This project focuses on designing a Virtual Private Network (VPN) within a university campus environment, specifically for Sheffield Hallam University. The core objective is to securely connect various departments, including Administration, Computer Science, Business School, Engineering, and Medical departments, using a Dynamic Multiple Virtual Private Network (DMVPN) design. The methodology involves research on remote VPNs, leveraging lease private lines, and utilizing Cisco certifications. The project utilizes Packet Tracer simulation to model the network, employing Cisco 1841 or 2900 series routers, servers, and necessary cabling. The design incorporates default and dynamic routing protocols (EIGRP), Generic Route Encapsulation (GRE), and VPN technologies to ensure secure data transmission. The configuration details are provided for each department's router, including IP addressing, interface configurations, and routing protocols. Furthermore, the project includes the implementation of VPN/IPsec configurations between the Computer Science and Business School departments, detailing the creation of ISAKMP policies, extended access lists, crypto transform sets, and crypto maps. The project concludes with verification tests, including ping tests to validate GRE and EIGRP configurations, as well as VPN functionality, demonstrating the successful implementation of a secure network design.
