If I understand the topology of your network correctly, all packets coming 
from the Internet through your ADSL router come back in onto your network 
and travel directly to the Windows machines without passing the linux router.
That's why they are not shaped.

One solution would be to put your linux router in between the ADSL router and 
your client network. You'll need to add a network card to you linux router, 
modify routing on the ADSL router to reach your client network, and point the 
default gateway on the linux router to the ADSL router.

In that case you are no longer using the ADSL router as a network address
translating router but simply as an ADSL modem.
