Yes you have, that's exactly my setup, i have a 100Mbps Ethernet 
connection to the router which has a 20Mpbs pipe to the net,
I only want to limit certain ips from using too much outgoing pipe

unshaped
So tc is a game of all or nothing ? i mean, i can't say to tc that all 
traffic except the one coming from X IP doesn't get a class ?
