So you want incoming + outgoing traffic to/from eth1 together bounded to
1mbit? Then you need the imq device. It's a patch for the kernel so you can
create a virtual device and a patch for iptables so you can redirect traffic
to that device. If you redirect incoming and outgoing traffic to the imq
device and limit the speed of the imq device to 1mbit, you have contol on
both in and out.
