[python-win32] Using win32com to access uPNP

[George Gonzalez]

I had the same problem.  I discovered that I needed to upgrade my 
router's firmware.  This added an icon for my router in "network 
places."   At this point though, double clicking on it gave me an error 
saying the "device you are currently trying to use is not currently 
available on your network"  I then went through the network setup 
wizard.  It all works now.  Note that this will only work if your router 
is nPnP compatible.  If it's not then you'll probably still get 
mappingPorts=None.  Here's my python terminal output:

 >>> theNatter = win32com.client.Dispatch("HNetCfg.NATUPnP")
 >>> print theNatter
<COMObject HNetCfg.NATUPnP>
 >>> mappingPorts = theNatter.StaticPortMappingCollection
 >>> print mappingPorts
<COMObject <unknown>>
 >>> mappingPorts.Add(1024, "TCP", 1024, "192.168.1.101", True, "IRC")
<COMObject Add>
 >>>
 >>> listPorts(mappingPorts)
0: True FTP 21 <router ip> TCP 192.168.1.100 21
1: False Telnet 23 <router ip> TCP 192.168.1.0 23
2: False SMTP 25 <router ip> TCP 192.168.1.0 25
3: False DNS 53 <router ip> UDP 192.168.1.0 53
4: False TFTP 69 <router ip> UDP 192.168.1.0 69
5: False finger 79 <router ip> TCP 192.168.1.0 79
6: False HTTP 80 <router ip> TCP 192.168.1.0 80
7: False POP3 110 <router ip> TCP 192.168.1.0 110
8: False NNTP 119 <router ip> TCP 192.168.1.0 119
9: False SNMP 161 <router ip> UDP 192.168.1.0 161
10: True IRC 1024 <router ip> TCP 192.168.1.101 1024

The original script is in the link below.  The current version has a 
typo.  You'll needed to change "mps[ii]" to "mappingPorts[ii]."
