IMQ
Hello
I have a server with a dsl connection on eth1 and local interface eth0.

Packet marking for ingress shapping and NET
Hi,
I have typical situation, local LAN with private addresses, translated
via NAT to internet. I need to shape ingress traffic (from internet to
local LAN) in several HTB queues accorting to destination (private not
public) IP. So I need mark packets to divide them to corresponding
queue. According to http://www.docum.org/stef.coene/qos/kptd/ I thing I
