Wasting your time, unless you own the entire route, it won't make any difference. QoS has to be enabled and set up on every node.
e.g
Route A (QoS) - ISP & Internet(No QoS) - Router B (QoS) = No QoS.
If running internal then that could be a different matter.
Only the truly stupid believe they know everything.
