A Virtual Private Network (VPN) is a service designed to establish a secure, encrypted connection to ensure privacy and anonymity while utilizing the internet. VPNs extend a private network across a public network, enabling users to securely send and receive data.
- Privacy and Anonymity: VPNs hide a user's browser history, IP address, and geographical location, enhancing security and preventing unauthorized access to personal data.
- Bypassing Geographical Restrictions: VPNs enable access to restricted content based on location, allowing users to visit otherwise unavailable websites.
- Remote Access: VPNs provide secure remote access to a company's network, facilitating work from home or while traveling.
- Public WiFi Security: VPNs protect users on public WiFi networks from hackers and cybercriminals attempting to intercept sensitive information.
- Tunneling Protocols: VPNs utilize tunneling protocols like OpenVPN, SSTP, and IKEv2 for data encryption and decryption.
- Encryption: VPNs use encryption to secure data transmitted over the internet, preventing unauthorized reading without the decryption key.
- IP Address Masking: VPNs replace a user's IP address with that of the VPN server, maintaining anonymity and preventing tracking.
- Remote Access VPNs: Allow individual users to securely connect to a private network over the internet.
- Site-to-Site VPNs: Connect entire networks in different locations, ensuring secure communication between them.
- Hardware VPNs: Physical devices providing VPN functionality, commonly used for added security in enterprise environments.

The Cisco 1941 routers are responsible for routing traffic within your network. They facilitate communication between different subnets and connect your local network to the internet.
The routers are configured to establish an IPSec VPN tunnel between them. This tunnel allows secure communication between the routers, even if they have duplicate LAN subnets. The VPN ensures that data exchanged between the routers is encrypted and secure.
The Cisco 2960-24 switch is used for local network switching. It provides efficient communication between devices within your local network, allowing devices to connect, communicate, and share resources seamlessly.
The server serves as a centralized hub for hosting various resources, including applications, databases, and shared files. It provides a platform for user authentication and authorization, ensuring secure access to network resources.
