I thought that features of UPnP is that the process on the inside can open a port on firewalls to allow traffic to that process. This makes things nice and easy for users as they don't need to understand about ports/firewalls etc, things just work.
On the downside, just because a device asks for a port to open, do you really want it to? Your CB Webcam could be a case in point. You may be OK for it to connect to your home recorder but if it can use UPnP and it's turned on at the router ...

Things are a bit more complex than this but I don't turn on UPnP on the router. If I have a service I want exposed I can do that manually.
