[LARTC] QoS and Nat

[LARTC] QoS and Nat

[Federico Figueroa C.]

I've been trying to make this work but don't know how yet.  The problem is
that I have a linux box doing the routing and nat for several private
subnets and we want to limit the bandwith for eache subnet to different
ammounts of the bandwith. For the upload was pretty easy, but for the
download of each one of them it's been a PITA, the mayor problem is that
the same linux box is a squid-proxy server and we don't want to loose the
speed boost they get when the object they want is already in cache so I
can't just set some tbf on the download side for each network because
they won't get the files from the cache fast. So my big question is how to
make a filter that can get all the packets going to network X but are not
originated from the router-squid-nat box.  Can anyone give me a hand with
this. Ingress works fine but for the whole system, I can't set an ingress
filter for each subnet because ingress sits on the outgoing interface and
the packets are already nated. Any ideas will be great.

					TIA.
