LARTC - May 2005 - Need some help

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 :)

You can shape from lan to router but only In ingress qdisc what is not a
good idea.
If you want prevent your lan users from uploading too much you can limit
your outgoing traffic on dev eth0.
