As a result, you have to shape to something below line rate as you are working with indirect methods that are far less precise than what would be ideal. As such, having the cpe equipment in the loop probably does not change things noticably in terms of managing downstream traffic. When you are managing the upstream traffic that you are directly controlling, you can shape it very close to line rate (just make it the WAN line rate, not the ethernet line rate to your cpe :-) ) there are things the cpe can do to hurt you, but if you can't replace it, you can't replace it. It won't be as bad as you are fearing. David Lang
