How VPN works

A VPN works by establishing a communication tunnel. We often speak of a tunnel since it allows information to be transmitted (from or to a server) in a secure manner. It is therefore a tunnel within a vast network that is the Internet.

During the routing of information, the data exchanged is encrypted from end to end to ensure confidentiality.

A VPN (network) service works based on the protocol to identify the sender and recipient of information. It then establishes a virtual path of routing, one speaks then of the protocol of " tunneling ". Tunneling itself consists of the encapsulation of data, its transmission and decapsulation on arrival.

VPNs use multiple protocols. Among them: the  PPTP (Point To Point Tunneling Protocol), IPsec (Internet Protocol Security), L2F (Layer 2 Forwarding), L2TP (Layer 2 Tunneling Protocol), SSTP (Secure Socket Tunneling Protocol), GRE (Generic Routing Encapsulation), etc.
