n2n: a Layer Two Peer-to-Peer VPN
Published December 8th, 2009 in FreeBSD, GNU/Linux, Networking and Unix. 0 Commentsn2n is a layer-two peer-to-peer 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 [...]
PacketFence is a fully supported, Free and Open Source network access control (NAC) system.
