Hello, what is the best way to do such thing:

Configuration:
addresses on 'Lan' interface are 10.0.0.0/16 and for ex. 212.212.212.212/27,
I have made simple queues for every client:

add name="xxx1" target-addresses=10.0.2.3/32 \
dst-address=0.0.0.0/0 interface=lan parent=none direction=both priority=8 \
queue=default/default limit-at=256000/256000 max-limit=512000/512000

And the same queues for public ip's

But the problem is, how to allow unlimited data transfer between 10.0.0.0/16 and 212.212.212.212/27 ?

Regards

create another queue like
then move it to the top of the list (can be clicked and dragged via winbox) and it will fire that with a maximum of 100mbps allowed.

Additionaly to the Forepoint post, I sugggest to use interface=all instead of specifying exact interface, if you want to apply bandwidth limitation to the both sides up/down.
