Tinc

Virtual Private Network (VPN) daemon

tinc is a Virtual Private Network VPN daemon that uses tunneling and encryption to create a secure private network between hosts on the Internet.

Because the tunnel appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This tunneling allows VPN sites to share information with each other over the Internet without exposing any information to others.

A single tinc daemon can accept more than one connection at a time, thus making it possible to create larger virtual networks, because some limitations are circumvented.

Instead of most other VPN implementations, tinc encapsulates each network packet in its own UDP packet, instead of encapsulating all into one TCP or even PPP over TCP stream. This results in lower latencies, less overhead, and in general better responsiveness and throughput.
