I’m currently looking at the miranda upnp tool (http://code.google.com/p/mirandaupnptool/). Is there a way for upnp to list all portmappings. I was able to forward ports an delete portmappings but I couldn’t find a way to list all mappings.
I’ve read somewhere that this mac os x tool does list all portmappings on your router
Some devices support the GetGenericPortMappingEntry method.
