What Is a VPN Gateway and How Does It Work
A VPN gateway acts as a secure entrance to the private network across the Internet. If we translate that in simple terms, it is a device or service that creates encrypted “tunnels” to transfer data between networks or devices. In that instance, imagine it as a well protected bridge. it will allow passing only authorized users to pass on their information that is kept hidden from the outsiders. VPN gateway can be hardware (for example, a special router) or it can be a cloud service. Usually, it’s located at the edge of a corporate network and used to control connections for remote users or branch offices. For instance, imagine that when you plug in your laptop to your company’s VPN gateway, it will give you some internal IP address and route your traffic like: ‘here is some public Internet, I am going to route through the company's internal network as if you’re in the company.’ It makes your remote device look like an insider to the company network instead of a random Internet user.
