The latter two are specifically for Shorewall setups, but may give some useful 

**BUT** there is a big limitation he needs to be aware of - you can only 
traffic shape *egress* traffic on an interface. This means that shaping 
outbound traffic is easy - you just setup a number of queues (one queue/HTB per 
guest) on the physical interface.

I believe you can shape inbound traffic by using an IFB. You force all inbound 
traffic to be routed via an IFB (a virtual interface) and can then setup 
traffic shaping on the egress of the IFB. It's not something I've done, so I 
can't say how to set it up.
