n2n

N2N is a P2P virtual private network that operates on a layer-two level. It provides users with IP visibility and allows them to be reachable with the same network IP address no matter where they are located. Unlike other VPN applications, N2N moves P2P from application to network protocol, meaning users can exploit features typical of P2P applications on a network level.

The architecture of N2N consists of two key components: edge nodes and supernodes. Edge nodes are installed on user PCs, creating a tun/tap device as an entry point to the N2N network. Supernodes act as a directory register and a packet router, allowing edge nodes to connect even behind firewalls.

To get started with N2N, users must download and compile the code, place their supernode on their preferred host and port, choose an encryption password, and decide on a network name and IP address for their edge nodes. Once configured, users can start their applications and test their N2N network.

Overall, N2N is a reliable and effective P2P VPN that provides users with IP visibility and security. Its architecture makes it a unique and powerful tool for connecting devices and networks, and its easy-to-use quickstart guide makes it accessible to even the most novice users.
