Can you elaborate please, I think I know what you're referring to but I'm not sure.

I don't really understand the attack in it's fullest so I hope you don't mind a simple link: http://www.bit-tech.net/news/bits/2013/01/30/upnp-vuln/1

From what I do understand, this attack has been known for a few years already though. I think I first heard about it at DEFCON about 3 or 4 years ago (though I've never been able to find the video of the talk since frown.gif )

Yeah I know all about the problems with UPnP

I was specifically asking about your comment "WAN connections inside the NAT" the way you wrote it implied that it was something different from the UPnP vulnerabilities, but I take it you just meant that UPnP facilitates the creation of a 1:1 NAT allowing communication from the WAN directly to a given host.

Just for clarification:

I mean: he does not understand a word I'm saying

So I do not understand what you guys are talking about

But it's cool nevertheless, I always read networking threads... trying to learn something...

That's how I learned anything about computers: autodidacticism

So no offence biggrin.gif

Well its either that, or tell users how to configure their NAT firewall to allow a port through... I guess they went with the former and let applications do it automatically.

"Port forwarding? What's a port? What does TCP or UDP mean? Which one do I choose? Hey, what are all those numbers!? Stupid computers, why can't they just do it themselves... Isn't that what they are for?"
