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. See COPYRIGHT for conditions and terms of redistribution. A current version of udptunnel.html is located at http://www.cs.columbia.edu/~lennox/udptunnel/.
