You need UPnP for a stateful firewall, whether it is mangling packets
with NAT or not.  I have an Xbox 360 behind an SSG-5 with no NAT, and I
can't play some on-line games unless I open up the Xbox IP in the SSG.

You can debate whether UPnP is the correct solution, but some solution
is needed (even with IPv6) as long as stateful firewalls exist.

I don't speak for anybody but myself - that's enough trouble.
