UDPTunnel by Jonathan Lennox; copyright 1999,2001 by Columbia University. UDPTunnel is a small program which can tunnel UDP packets bi-directionally over a TCP connection. Its primary purpose (and original motivation) is to allow multi-media conferences to traverse a firewall which allows only outgoing TCP connections. Source code for Unix is available from <ftp://ftp.cs.columbia.edu/pub/lennox/udptunnel/>. See udptunnel.html for installation and usage instructions.
