Transport-layer distributed reverse/forward proxy and tunneling solution.
PortFusion is a minimalistic, cross-platform, transport-layer distributed
reverse / forward proxy and tunneling solution for TCP released
under GPLv3. A single package that makes the most of each platform by
tapping into their unique capabilities, combining this power with an
intuitive interface, beautiful design and Haskell's excellent support
for unprecedented levels of concurrency and parallelism. It strives
for the smallest source code size while delivering maximum throughput
with near-zero overhead.
