I notice that you have a REJECT policy for fw->loc. That being the case,
you need the following rule to allow UPnP to work from the local LAN:

ACCEPT  $FW     loc     udp

The reason is that Netfilter connection tracking doesn't work with
Multicast, so you must explicitly accept the firewall's responses to
Multicasts from the LAN.
