This is UPNP -- you must have an old version of Shorewall as later 
versions had an entry for this in the common.def file. You can kill these 
by creating /etc/shorewall/common (if that file isn't there already) and 
add the following to it:

        run_iptables -A common -p UDP --dport 1900 -j DROP

Or upgrade your Shorewall.
