Abstract

A computer network is a collection of several computers and even millions of computers, called a computer network, it can be a local or long distance network, a local network or called a LAN (Local Area Network) and a long distance network or the internet. Internet service is a facility that cannot be separated from human life, so we need a way to make the most of the internet. Virtual Private Network (VPN) is a way to make a network "private" and secure by using a public network such as the internet. VPN can send data between two computers that pass through a public network so that it seems to be connected point to point. The data is encapsulated (wrapped) with a header containing routing information to get a point to point connection so that the data can pass through the public network and can reach the final destination. A Virtual Private Network that can connect the public network with the local network, so that it becomes the basis for tunneling implementation on the SMA Negeri 1 Bantarsari server. The problem faced at the school is because the server that the school has cannot be accessed through the public network, for that reason the author implements a VPN tunnel on the school server network. According to the user's view, a VPN connection is a point to point connection between a computer user and a corporate server and data is sent over a "dedicated" network, even though this is not the case.
