Update…
While searching through the forums, I came accross this:
http://forum.pfsense.org/index.php/topic,9782.0.html
I enabled the shaping rules, rebooted the box, and, SHAZAM!, UDP 4569 traffic is now redirected to the proper queues...
Don't know if this is a BUG or a Feature, but at least I can prioritize my VoIP traffic..
Thanks
