Tailscale is an open-source zero-configuration VPN and networking solution that makes it simple to create secure, private networks across devices by leveraging WireGuard under the hood. It lets users connect computers, servers, mobile devices, and cloud instances together with peer-to-peer encrypted tunnels without dealing with complex firewalls, NAT rules, or key distribution headaches. Instead of traditional VPN server infrastructure, Tailscale uses a coordination service to authenticate devices and exchange connection information, enabling automatic NAT traversal and minimal manual setup. The project includes a daemon (tailscaled) and a CLI tool that run on major operating systems, and it also forms the basis for the official clients on platforms like iOS and Android, though those have GUI wrappers not fully in this repository.

...Hence, it adopts the design goals of the WireGuard project, to be simple and easy to use. Thanks to Interactive Connectivity Establishment (ICE), cunīcu is capable of establishing direct connections between peers that are located behind NAT firewalls such as home routers. In situations where ICE fails, or direct UDP connectivity is not available, cunīcu falls back to using TURN relays to reroute traffic over an intermediate hop or encapsulate the WireGuard traffic via TURN-TCP.

...Linux host (including desktop Linux,Android phone/tablet,OpenWRT router,or Raspberry PI) with root account or cap_net_raw capability. ICMP/FakeTCP headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. In ICMP header mode,udp2raw works like an ICMP tunnel. UDP headers are also supported. In UDP header mode, it behaves just like a normal UDP tunnel, and you can just make use of the other features (such as encryption, anti-replay, or connection stalization).

Campagnol is a decentralized VPN over UDP tunneling. It uses UDP hole punching to open connections through NAT/firewall and OpenSSL's DTLSv1 implementation for mutual authentication and encryption.
