Editing VPN


A [[Wikipedia:Virtual private network|VPN (Virtual Private Network)]] is a dedicated connection to a LAN (Local Area Network) via the internet. When connected via a VPN connection, a Local Area Network is not restricted by the limitations regarding physical cables, and the local network can therefore connect to the internet through a VPN client.


VPNs can be typically characterized as host-to-network or remote access by connecting a single computer to a network or as site-to-site for connecting two networks.
