In this article we will take a look on how to install VPN server on Windows Server 2012 R2. VPN (virtual private network) technology is used to create a direct connection between computers that placed in different subnets. For example, you can use VPN when it is necessary to set up a small computer network of companies whose employees are working remotely. It also can be useful in a situation when you want to play computer game with your friend who lives in another city.
VPN uses internet transport protocols TCP, UDP and has several types of implementations — PPTP, L2TP, OpenVPN. In this article we will consider a VPN solution for Microsoft Windows based on PPTP. This protocol is not the best solution because of its low security level, but it is the simplest and fastest way to create a connection using only the built-in features of your operating system without external apps installation.
Follow this step by step guide.
Before you begin the installation of VPN, ensure that port 1723 is open for TCP PPTP in your firewall.
At first open your Server Manager and click on Add Roles and Features.
Now select Role-based or feature-based installation option and click on Next.
