This is a simple module that allows you to reroute network traffic from one port to another. Something along the lines
$ mkfifo pipe
$ nc -l -p 6565 <pipe | nc 192.168.0.104 8181 >pipe
except that the python version does not need respawning each time the connection drops, and can handle multiple connections.
After installation (python setup.py install --user or something similar) you can reroute the network traffic as
$ rudicsrerouter 6565 192.168.0.104 8181
which would forward all traffic arriving at 6565 to 192.168.0.104:8181, allowing bi-directional communication.
