the technical name for such a thing is uPNP. I've explained why it's
worthless and dangerous on the pfsense list in the following thread,
so I won't repeat myself here.
One comment on that reply, I'd say it's a huge risk in any
environment, not just corporate. Think worms, viruses, trojans, and
other malware that could open a port in your firewall so outside
attackers could talk directly to whatever junk is on your machine(s).
