udpproxy
UDP proxy utility like udpxy implemented with asynchronous I/O and SSL/TLS support.
Better buffer management model, comparing to udpxy, provides more reliable data transfer. Single threaded application (like Node.js). Can be used as C++ library for easy embedding into applications (Boost.Asio required).
