In the Qos classifier, use the subnets as the src, and point it to the test class, this will limit the upload from lan clients to the sites.
Reverse it for the subnets to be the destination, and point it to the same class, to limit the download speed.
And don’t forget to save the changes on the classifier at the top.
And, don’t forget to add the class to the correct interface as well on the main qos/interface manager section. The download interface will be your lan side, and the upload interface will be the internet/wan side, and save the changes at the top as well.
