How to use UPnP in Python?

Question

Universal Plug and Play

There is a certain port that you want to open to the outside. By default, all ports on the computer are open, but outside they are blocked by 1 or 2 routers (with UPnP support - otherwise how would Skype or torrent work?).

Accordingly, it is not clear what needs to be written in the code in order not to forward ports on the router, and the port to which a connection is expected from the outside was opened (forwarded) by itself.

Answer 1

For example here (miranda-upnp) see how it works. There is a readme.html in downloads/ which shows how to create a portmapping.
And then you can use this library (pyupnp) to implement portmapping in your program.
