Requirements: Linux 2.2.x

UDP Bridge is a transparent proxy for UDP traffic, designed to use the transparent proxy support of the Linux 2.2.x series kernels. It provides two-way proxying of UDP packets, to avoid the port number mangling that occurs with Linux IP masquerading.

This program was actually developed to solve a problem with handling Playstation 2 network traffic through a Linux firewall. According to testimonials, most games worked fine with this kind of configuration, but the one that I had tried (ATV Offroad Fury 2) would not work. The problem was apparently the UDP port mangling done by Linux IP masquerading, hence the need for this proxy.
