Hi people!
After three weeks of intense research and to bother some great guys in the forums( ;D) I realized that the way to accomplish that I want it is easy(i am lair :D) to do with a pfSense 2.0 box, and almost impossible to do with pfSense 1.2.3.
Finally I'm be able to configure the traffic shaper(ufffff) and I want to share my experiences with both newbies and old-mans in this matters.
When I have a five(and I will have), I will post data of my network topology, the requeriments for my network and a guide how I accomplished the requeriments.
