Traffic Shaper - Traffic Joing Correct Queue, Ignoring Weights

[mrrodge]

Title says it all really.  Not sure what I'm doing wrong.

I've had it working great in the past but for some reason can't get the behaviour I'm looking for.

I have a 73/18 connection and a downloader using port 563.  I want to allow the downloader to use the full bandwidth when it's available but when something else saturates the connection throttle it back to 10mbit/sec guaranteed.

I've set up two pipes, Up/Down with speeds 18/73mbit/s.  I've created three queues, Up, Downloader and EverythingElse.  Up is weighted 1, Downloader is weighted 10 and EverythingElse is weighted 63.  I've then got two rules, one with all default options but port 563 and pointing to the Downloader queue, sequence 1 and another with all default options, Sequence 2, pointing to the EverythingElse queue.

Looking at the status page when testing the shaper is doing something because the traffic shows up in the right queues but no matter what I change the weights to the bandwidths being use don't change.  The Downloader queue seems to get the most bandwidth.

Any ideas?

Thanks.
