[LARTC] making a traffic shaper for wireless users

["Alexis" <alexis@tpys.com.ar>]

Hello all,

Im new using tc, ive been reading the howto at least 2 or 3 times, but there's a
lot information to aquire all of it quickly.

I've installed a linux box as firewall for a wireless Network in a hotel, this
box is a radius for the access points and it uses iptables to redirect and
permit/deny the customers to use the net. So it uses iptables to count the bytes
to restrict the user using the bytes transferred.

Now i have to create a different bandwith restrictions, i've testing using
iptables to mark the users and then restrict the bandwith, but it was in a lab
scenario, my question is


if i create suppose a classifier for 64kbps, 128kbps, 256kbps and so on. do i
have to create different classifiers for each customer? or just sending 2 or
more customers to the 128kbps lane, both of them will have 128kbps to use and
not 128/users?


to restrict incoming and outgoing, i need to set a classifier in both
interfaces? for incoming traffic the classifier goes to the LAN interface and
for outgoing traffic in the WAN? of course switching the source/destination
information at the iptables rules used to mark.


Thank you.
