I have attached one rule, but there are many clients like this. No matter the queue, they uses at least 100 kbps of upload.

Could you post you setting detail of the simple queue ?

We can not see any issue about you simple queue from your picture.

Make a torch to this address

M.

Are you setting both the default AND max value to 32k? (they're on 2 separate tabs)

I had the same problem
yesterday I buyed new MT v3.0rc5 for my new sata and just restore backup from 2.9 to 3.0rc5 (but with same problem with p2p)
today made a fully reset and configured it from beginning(without restore)
For now queues working ok but still can't limit Ares traffic

You cant limit all encrypted traffic, BUT, make mangle rules, first mangle with connection mark, then make packet mark with firstly created connection mark for IP or range of IP addresses, in that way you can limit every user with rate that you want.

At least it is how I did it, and it works fine.
