It would be quite some work to setup a configuration, there are a lot of hosts that need to be limited.

After few tests I managed to isolate the problem (kinndof) - if I use just one class, best-effort for example, and put all filters/qdisc in this one everything works fine. But I really need to separate big clients (premium) from small ones (best-effort) and to shape management/bgp traffic separately from those 2. atm the only separations is made after prio value: bgp 0, management 1, premium 2, best-effort 3 and default 7. Thanks for the help! p.s. I'm working on a romanian translation for LARTC. I have about 1/4 of it till now. If there are any romanians on this list willing to help it would a very nice thing to do for the community. Also translating this great howto it's a study itself so you can get also some solid knowledge besides the Glory:) -- + Lorin + I tought I taw a putty cat...I did!
