A VPN client is typically a PC-based software or hardware complex whose network software is modified to encrypt and authenticate traffic it exchanges with another VPN client, VPN server, or VPN security gateway.

• A VPN client is typically a PC-based software or hardware complex whose network software is modified to encrypt and authenticate traffic it exchanges with another VPN client, VPN server, or VPN security gateway.
• A VPN server consists of a software or software-hardware complex installed on a computer, performing the function of a server. The VPN server provides protection of servers from unauthorized use of external networks and the establishment of secure connections with individual computers and computers in local network segments protected by suitable VPN products. VPN-server is a functional analogue of VPN-client server platforms. It is primarily distinguished by its extended resources, which support many connections with VPN clients. A VPN server can also facilitate connections with mobile users.

VPN security gateway. (Security gateway) is a network device that connects to two networks and performs encryption and authentication tasks for a large number of hosts located behind it. The VPN security gateway is placed in such a way that all traffic destined for the internal corporate network passes through it. The address of the VPN security gateway is shown as the external address of the incoming tunneled packet, while the internal address of the packet is the address of the specific host behind the gateway. A VPN security gateway can be implemented as a separate software solution, a separate hardware device, as well as routers or firewalls with VPN functions.
