Thanks for this hint. From the thread (http://zgp.org/pipermail/p2p-hackers/2006-April/003804.html) it looks like that different people made different experiences. Probably it would be a good idea to write a small UPnP-Capability-Test-Programm so that we can collect data for a survey. I think it is an unanswered question if and how well UPnP works. My perception is that it works pretty well because it is supported by many routers and a lot of software in UPnP-enabled. However, may be I am wrong. What do you think about this?
Of course, this evaluation program should not be part of freenet, instead it should be a separate program probably announced on the freenet website?
