Hello again! Well, i should maybe post everything related to this problem.
The class 1:3 which has rate as its father 1:2, just because it is the
traffic between the local network and the server itself. I have some
services like mail, http, samba which I want to be accessed from local net
at  maximum speed. Now when you know the details,  could this be the real
problem ? I remember I deleted one time everything , remained only those two
classes , and it was the same thing. I just believe that this problem is
caused by a mistake, but I dont know which one. Its interesting, did anyone
configure the prio in htb and it worked..??

Andreas, how did you create such a descriptive image..is there a tool or
something??
