Based on miranda-upnp: https://github.com/0x90/miranda-upnp
xerxesUPnP is an easy-to-use python library for managing UPnP port forwarding. The library will automatically detect your WANIPConnection device, then allow you to add/remove port forwarding rules.
To test your UPnP device, clone this repository with:
cd ~ && git clone https://github.com/Xerxes3rd/xerxesUPnP.git && cd -
(or, if you've already cloned it, run: cd ~/xerxesUPnP/ && git pull && cd - to get the latest version)
Then run the test app send the output to sprunge:
~/xerxesUPnP/upnp_test.py | curl -F 'sprunge=<-' http://sprunge.us
Then, send the resulting link to someone (probably me) for analysis.
