G'day Chris,

So, what happens when some malware gets installed on a PC which is allowed to open ports on the UPnP
device and then starts communicating over those?

UPnP has no place on a gateway/security device.  It is a vulnerability waiting to be exploited by
any malware author who cares to take advantage of it.  It will never, ever be used on gateway
devices in any of our client sites (including our own).

A good UPnP implementation means that the code isn't even present on gateway/edge security devices.
