Simple Queues don’t work properly...

I have heard this more than once, my MikroTik RouterOS Simple Queues don't work properly.  In a simple queue, “target” option is the only option that determines the flow direction of a simple queue.  Since the default value is 0.0.0.0/0, leaving it at that value creates an issue.

• If a target is not specified (is 0.0.0.0/0), all traffic will be captured in the download part of the queue, as everything is download for 0.0.0.0/0.
• This means the queue will not deliver the amount of bandwidth you are expecting.
• Using the “dst” option is only an additional filter, it doesn’t determine the direction.

I did some tests using different values for target.  First, the incorrect target of 0.0.0.0/0. Notice this is a 3Mx3M queue and we aren't getting even close to that on download:  Now, I changed the target to the IP of the test workstation. As you can see the queue operates as expected now, about 3Mx3M.  Finally  I changed the target to the interface.  Same result, 3Mx3M:  Set that target, don't accept 0.0.0.0/0 and your MikroTik simple queues will work as expected.
