oh az nerazbiram (gledam4ei v net listata maj nqmaha vreme da consult), no in 
my humble opinion maj imash bad syntax za Token Bucket Filter. Vmesto Kbit, 
maj trebe da e kbit. Osven tova tova "mtu" ne e li golqmo ili "quantum"-a ne 
ti e set-nat pravilno? (ot LARTC howto za Stochastic Fairness 
Queueing,neznamdali vazhi i za TBF: Amount of bytes a stream is allowed to 
dequeue before the next queue gets a turn. Defaults to 1 maximum sized packet 
(MTU-sized). Do not set below the MTU!)... ama ne to kvanta si s kvant, 
zavsi4ki trebe da ukazva ednakvovliqniezavsi4ki queue disciplines :-/)

e da eto i CBQ discipinata pla4e za bad quantum. Porazgledaj pak LARTC za 
syntax-a na syotvetnite qdics's. Ina4e majne pravish logi4eska greshka... a 
samo 1 vypros: ne e pravilnopyrvo da se --set-mark-va v PREROUTING (kakto si 
go napravil) i posle da se queue-va s sysotvetnata disciplina, stoto ti maj 
pyrvopodavash qdics commands i posle --set-mark-vash? ili kernela samsi gi
