UPnP-IGD using the miniupnpc python package doesn't work.

15063 - Creator's Update

I'm trying to use the python version of miniupnp for IGD (port forwarding), and it seems as though it isn't working when hosted in WSL.

They have a test script here: link

Installation of the test script:

sudo pip install minipnpc
curl https://raw.githubusercontent.com/miniupnp/miniupnp/master/miniupnpc/testupnpigd.py > main.py
python main.py

This should print an address, eg http://67.171.123.456:12345
In another terminal, run curl http://67.171.123.456:12345 with the address from before. Or you can open it up in your browser. Or whatever you want - though my Android phone doesn't seem to be able to get the page.

Expected output:

(with your IP though)

What actually happens:
The curl just hangs.

I can see that the port is forwarded in the router's UPnP settings just the same as it is from the working version on my linux box on my desk, so I figure there's a chance there's some WSL has a part to play.

@zadjii - Does your port, i.e., 12345, listen? I think you could check it by "netstat -aq" command. Open bash console and cmd console. Command "python main.py" in bash console and "netstat -aq | findstr 12345" in cmd console. In my case, #1498 (comment) , "It looks like your Anti-Virus was blocking the program from listening." You might not be in a similar case but... it could be better to check tcp port listen or not.

Curiously enough, netstat didn't show anything, though I was able to curl the tester using the internal port.

@zadjii - I said command netstat in cmd.exe console. There is an another issue of netstat, #1488, that I cannot be sure whether it be fixed. There seems many network related issues like #1554, #1498, #1385 and more. It could be helpful to collect log following #1853 (comment) for clarifying issue; In that comment, @sunilmut said the command "nc -4 -l 127.0.0.1 8000" but your tcp port is not 8000, so command like this - "netstat -qp tcp | findstr 12345" in cmd.exe console if your port be 123435.
