Raspberry Pi – VPN server with PPTP

In this document we will see in a very simple way how to mount a VPN server on our Raspberry Pi, it will be a PPTP server that will be something basic to connect from the internet to our homes/small businesses, quite useful, especially if we have services that we want to access and do not want to give public access. If we don't have a fixed public IP, it would be ideal to combine it with the NO-IP client on our Raspberry!!!

Setting up a VPN or Virtual Private Network on Windows using PPTP protocol

With this, What we will achieve is, from a physically separate location to our company's LAN, house… connect to it and see all the computers on the network. It is a free connection that we will use once we are already connected to the Internet. You need to have these ports open and mapped against the routing server (VPN), Port 47 GRE (failing that, TCP) and the 1723 TCP.
