I've got three ADSL lines. ADSL1, ADSL2 and ADSL3. When packets arrives I mark them in IPtables with 1, 2 or 3 so I can know in my LAN interface what interface each packet arrived on at the INTERNET interfaces, so each packet can be put into a HTB class that represent each ADSL bandwidth. In addition to this I also match for dest IP in LAN, and put each IP in a different HTB class with different rates, ceil and prio. Also I use SFQ in HTB. This is it for shaping incoming packets from Internet on ADSL 1-3, to my single LAN. Now I want to shape what is coming from LAN going out on Internet's ADSL lines. This I do by making three HTB qdiscs, one for each ADSL line. As my LAN is NATed I don't know from whom I got a packet, so I use mark in IPtables to identify an LAN IP with a HTB class. This is how I shape. I don't know what is more clever, and I don't know how IMQ could help me to do this neater, but I really would like to know. regards, Kjell
