Using an ideea from Matt's Codecave I made a small module to control the router - blog announcement.
The solution works both on Windows and Linux. Use it with caution on private networks: it will expose your redirected ports to anyone from Internet.
On Linux you must install netifaces: pip install netifaces, on Windows it works without netifaces.
License-free software.
Feel free to use this software for both personal and commercial.
A sample webserver in python with bottle py is included into repository.
import os
from upnpgwcontrol import UpnpGWControl
PORT=os.getenv("PORT",8089)
gwc = UpnpGWControl()
if gwc.findGateway(5):
print "Gateway ip =", gwc.gateway_ip
print "Local ip =", gwc.myip
gwc.GetExternalIPAddress()
print "External ip =", gwc.myexternalip
gwc.DeletePortMapping(PORT)
gwc.AddPortMapping(PORT, PORT, "TCP", "Webserver port {}".format(PORT))
#start server
print "Start Server, port=",PORT
...
...
else:
print "Error findGateway"A better sample is included in module.
