If you use a VPN to secure your online privacy and data, you might have encountered the terms VPN gateway and VPN concentrator. But what are they and how do they differ? In this article, we'll explain the basics of VPN security architecture and design, and how these two devices play different roles in creating and managing VPN connections.
A VPN gateway is a device that connects a local network to a remote network via a VPN tunnel. It can be a router, a firewall, a server, or a dedicated appliance. A VPN gateway encrypts and decrypts the traffic that passes through the tunnel, and also handles the authentication and authorization of the VPN users. A VPN gateway can support multiple VPN protocols, such as IPSec, SSL, or L2TP, and multiple VPN tunnels, depending on its capacity and configuration.
A VPN gateway typically refers to a device that connects different networks and facilitates secure communication between them. On the other hand, a VPN concentrator is a specialized type of VPN gateway that specifically handles a large number of simultaneous VPN connections, optimizing and managing the traffic efficiently. In essence, while a VPN gateway serves as a broader term, a VPN concentrator is a specific type of gateway designed for handling multiple connections.
A gateway by definition connects two or more networks thereby also providing routing (L3) and firewall functionality in addition to VPNs. On the other hand a concentrator is only a L2 "termination" device which handles a large number of VPN connections over a single ethernet port. VPN Concentrators should NOT be placed at the perimeter of your network because of security risks.
