The port is available and you need to compile it with a C/C++ compiler. #edge node> edge -d n2n0 -c mynetwork -k encryptme -a 1.2.3.4 -l a.b.c.d:xyw You need to specify the tap interface name with -d. Now test your n2n network: #edge node1> ping 10.1.2.2 #edge node2> edge -a 10.1.2.2 -c mynetwork -k encryptme -l a.b.c.d:xyw #edge node1> edge -a 10.1.2.1 -c mynetwork -k encryptme -l a.b.c.d:xyw

Decide what IP address you plan to use on your edge nodes.

Note that you can use your supernode/edge nodes to handle multiple networks, not just one.

Decide the network name you want to use.

Decide what encryption password you want to use to secure your data.

Suppose you put it on host a.b.c.d at port xyw. Each PC can have multiple tap interfaces, one per n2n network, so that the same PC can belong to multiple communities. This application is basically a directory register and a packet router for those nodes that cannot talk directly.Įdge nodes talk by means of virtual tap interfaces. Practically each edge node creates a tun/tap device that is then the entry point to the n2n network.Īn supernode: it is used by edge nodes at startup or for reaching nodes behind symmetrical firewalls. The n2n architecture is based on two components:Įdge nodes: applications installed on user PCs that allow the n2n network to be build.

n2n networks are not meant to be self-contained: it is possible to route traffic across n2n and non-n2n networks.

Firewalls no longer are an obstacle to direct communications at IP level. from outside to inside) so that n2n nodes are reachable even if running on a private network.

Ability to cross NAT and firewalls in the reverse traffic direction (i.e.

Each n2n user can simultaneously belong to multiple networks (a.k.a.

Encryption is performed on edge nodes using open protocols with user-defined encryption keys: you control your security without delegating it to companies as it happens with Skype or Hamachi.

An n2n is an encrypted layer two private network based on a P2P protocol.

used to implement the https protocol) to network protocol, n2n moves P2P from application to network level. In a nutshell, as OpenVPN moved SSL from application (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. This means that users can gain native IP visibility (e.g. N2n 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.
