A VPN server is a regular server configured with VPN software. However, there is a difference between a VPN server and a regular server. VPN server has more logical and physical communication ports. The VPN server provides VPN connections and services to remote VPN clients or local VPN clients. Usually, VPN servers will use one or more protocols for connection and communication, such as point-to-point protocol (PPP). When the client wants to connect to the VPN server, the server must authenticate itself first before being granted access to the VPN.

VPN server software will be installed on the VPN server system. The purpose of this installation is to help the VPN server process and operate the hardware with other components. Along with that, this software also has the function of providing management and security capabilities when establishing a relationship between the server and client. VPN server software uses a number of common VPN protocols such as PPTP, OpenVPN, IKEv2, SoftEther, SSTP and L2TP for different connection types.
Role of VPN server

When you establish a connection through a VPN, your role becomes that of a user (client), using the client application to encrypt requests before they are sent to the internet service provider (ISP). your. This client program simply transforms your messages before they go through the tunnel to the ISP. Because the VPN acts like a tunnel and only the object at each end of the tunnel has the ability to decrypt data, your ISP will not be able to track the request or the actual information of the encrypted data. .
