disabling UPnP port 5000

Hi, I have had a port scan of my SuSEFirewall2 done at grc.com, they reported everything is stealth, except port 113(ident) and 5000(UPnP), which are closed. I can see where 113 is controlled in the firewall script, but I can't figure out where UPnP 5000 is controlled. Where do I disable that? -- $|=1;while(1){print pack("h*",'75861647f302d4560275f6272797f3');sleep(1); for(1..16){for(8,32,8,7){print chr($_);}select(undef,undef,undef,.05);}}
