Chapter 1. Point-to-Point Networks > Shortest setup possible

Shortest setup possible

This recipe will explain the shortest setup possible when using OpenVPN. For this setup two computers are used that are connected over a network (LAN or Internet). We will use both a TUN-style network and a TAP-style network and will focus on the differences between them. A TUN device is used mostly for VPN tunnels where only IP-traffic is used. A TAP device allows full Ethernet frames to be passed over the OpenVPN tunnel, hence providing support for non-IP based protocols such as IPX and AppleTalk.

While this may seem useless at first glance, it can be very useful to quickly test whether OpenVPN can connect to a remote system.
