How Does a Windows VPN Server Setup Work?

A VPN (Virtual Private Network) creates an encrypted tunnel between a remote device and the VPN server.

The general process works as follows:

1. A remote user launches a VPN client.
2. The client connects to the Windows VPN server Setup using a supported protocol.
3. The server authenticates the user’s credentials.
4. An encrypted tunnel is established.
5. The user can securely access approved network resources.

This encrypted communication helps protect sensitive information from interception when using public or untrusted internet connections.
