Stuntman
STUNTMAN is an open source implementation of the STUN protocol (Session Traversal Utilities for NAT) as specified in RFCs 5389, 5769, and 5780. It also includes backwards compatibility for RFC 3489. Source code distribution includes a high performance STUN server, a client application, and a set of code libraries for implementing a STUN client within an application.
The current C++ code base compiles using gcc/g++ for most UNIX distributions including Linux, MacOS, BSD, and Solaris. A Windows port via Cygwin is available now.
