[LARTC] Need some help

[kinto <mlist@email.it>]

Hi all, I have read the larc howto and I need to apply a traffic shaper 
with this configuration:


router / two interface etho and eth1

lan

lan is on eth1 and on eth0 I've the dsl connection (1.2 Mbit / 256 kbit)



I need to limit the bandwith towards lan and I've thought at HTB and 
tcng. I write the script belove. I want limit the p2p and ftp (ssh and 
irc) connection at 15 kBps (128 kbps) and the other type of traffic at 
32 kBps (256kbps). Is the script right?
Moreover I want understand better how htb work: I can shape the traffic 
router->lan but I can't shape traffic lan->router, is it right? In this 
way I can limit the bandwidht towards lan, but I have the bandwith 
towards router always full.
Thanks



P.S.: sorry for my very bad english :)
