n2n 1.3.2 Description:
n2n is a layer-two peer-to-peer (P2P) virtual private network (VPN) which allows users to exploit features typical of P2P applications at network instead of application level. This means that users can gain native IP visibility (e.g. two PCs belonging to the same n2n network can ping each other) and be reachable with the same network IP address regardless of the network where they currently belong. In a nutshell, as OpenVPN moved SSL from application (e.g. used to implement the https protocol) to network protocol, n2n moves P2P from application to network level. The n2n architecture is based on two components: - edge nodes: applications installed on user PCs that allow the n2n network to be build. Practically each edge node creates a tun/tap device that is then the entry point to the n2n network.
