n2n (network-to-network) is a layer-two
peer-to-peer virtual private network (VPN) that
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.
