Asymmetric QoS Configuration

[SupaJMember]

Setup:

Internet — eth01 — ZeroShell — eth0 — LAN.

I have an asymmetric Internet cnx: 1Mb/s down, 256kb/s up.

Max bandwidth on eth01 is set to 256kb/s and on eth00 it is 1Mb/s. In Fulvio’s explanation here he says that you must add the QoS classes to both interfaces. However if I set an upload cap of 50kb/s on bittorent traffic it will also limit bittorent downloads to this same speed, which is not what I want.

Questions:
(a) Is it necessary to add the same QoS classes defined to both interfaces? Can I create different QoS classes for eth01 and eth00?
(b) Is it really necessary to activate QoS on eth0. Let’s say I want full LAN speed in/out of the ZeroShell box. What effect will it have on BWM if I do not activate it?
(c) If QoS is enable on both interfaces, and the same classes are assign to both, how do I assign separate upload and download speeds for a particular type of traffic e.g. bittorent?

After applying a class to a network interface, press [Modify] button to apply Local Parameters. In this case, the class parameters are not imported from the class manager but are customized for the interface.
