Stunlock

Stunlock is a peer-to-peer NAT traversal utility. Connect with private-network peers as if you were on the same local network. There are no application-owned servers involved – the core idea is to leverage user-provided services. You bring your STUN server (self-hosted or public). The app will use the STUN host to discover your public IP address and connect to peers.

Features

• Virtual network interface emulates a private network
• Configurable STUN endpoint used for NAT mapping discovery
• Tunnel IP datagrams between peers through UDP hole punched channel.
• Lightweight and OS-themed desktop application.

Disclaimer

The project is in early development. Since there are no relays involved, symmetric-NAT peers will not be able to connect to each other. This may include mobile-networks and some home routers. There are plans to implement relays in the form of configurable TURN servers to overcome this issue.
