This question comes up pretty often. Conceptually, we can do it in two ways. 1. All outgoing traffic is shaped on the interface which is internet facing say eth0. Then the incoming traffic will go the LAN thro' eth1. In this case shaping outgoing traffic on eth1 is nearly equivalent to shaping incoming traffic on eth0 ( assuming all traffic is for the LAN and not for the host). Another option to limit incoming traffic on eth0 is to use the ingress qdisc and police rates to a cap and shape the bandwidth utilised on eth1 to the LAN. In the case above, bandwidth is apportioned as incoming and outgoing separately. In the case of many ISPs, they would like to allocate bandwidth for incoming + outgoing instead of dividing what is allotted further between incoming and outgoing. In such a case, IMQ device is used. Shaping IMQ will shape the aggregated traffic of incoming+outgoing.
