I am currently running the following script on an internal machine to

I am trying to move the script to my nat router (ipcop with 2 nic cards)
so that it shapes the whole network and not only the outbound of 1 box.

I have cable modem -> ipcop (eth1) >(eth0 - 192.168.1.1)  >
192.168.1.100 and 192.168.1.101.


Does this mean the cable modem is on eth1? You need to use whichever
device is connected to the cable modem. Based on the above, it seems
like eth0 is for the local network and yet all of your rules below are
for eth0.  This would only be useful for shaping incoming bandwidth
from the internet, not bandwidth to the internet.

The scripts works great running on 192.168.1.101.  But I cannot get it
to work on either of the ipcop interfaces.

Does it have something to do with NAT ?

Since you're not matching on addresses, it shouldn't have to do with
NAT. I also noticed in your rules you have a local traffic 100mbit
class, if your cable modem is the only thing connected to the pc you
shouldn't have such a class as it serves no purpose and could break
things.

I have changed the eth0 to eth1 and changed the 100mbit root class to 1mbit.

Still doesnt work.
