It has come to our attention that a rogue botnet is currently scanning random public IP addresses to find open Winbox (8291) and WWW (80) ports, to exploit a vulnerability in the RouterOS www server that was patched more than a year ago (in RouterOS v6.38.5, March 2017).
Since all RouterOS devices offer free upgrades with just two clicks, we urge you to upgrade your devices with the “Check for updates” button, if you haven’t done so within the last year.

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.
