OpenVPN is a free and open source (GPL) virtual private network (VPN) program for creating point-to-point or server-to-multiclient encrypted tunnels between host computers. It is capable of establishing direct links between computers across network address translators (NATs) and firewalls.

It is not IPSec or PPTP.. OpenVPN is it's own software thing that can work using one IP Port (UDP or TCP.)


In Short... With OpenVPN computers/networks can communicate privately over public networks like the Internet.

It seems to be command lineish with text editing config rather then UI based config.
