QoS / Limiting

Hi Guys,

We’ve got a network as follows:

The ADSL modem connects to Port 2 on our RB711GL
The RB711GL dials a PPPoE connection. (ADSL Line & Account speed = 4096Kbps down / 512Kbps up)
The RB711GL port 5 connects to the RB800.
RB800 connects it to our wireless network.

We’ve got 4 clients, and the client IP Ranges are:
192.168.1.0/24
192.168.2.0/24
192.168.3.0/24
192.168.4.0/24

NOW, the problem!

I’m trying to implement limiting to the ADSL line. i.e. split it to 1024Kbps Down / 128kbps Up for each client.
I tried PCQs, but the problem comes in, as soon as you run a speedtest.net the ICMP jumps for another client.
This affects services dependant on ICMP (Online gaming)
After doing some more research I assume I need to do QoS now as well.
So I’ve tried and tried and tried and gave up. So much so, I’ve scratched the whole config!
I’ve watched the QoS workshops on tiktube as well as went through the PDFs, and I’m still lost.

Could somebody please assist me?

Thank you for your reply acim,

I’ve attempted the one line you’ve posted without much success…

Any more information?

Did you read the page I sent the URL? Have you inserted the mangle rules and queue tree in you routerboard?

Hi acim,

Yes I have.
I created all the Mangle rules.
I created the Queue Tree based on my PPPoE interface and my Max Limit (4096k)

I then ran a continuous ping to google.com
I ran a speedtest.net and watched as the ping spiked on download and upload.

I tried the expansion script from your link as well.
I just modified the interface in the script to point to my PPPoE interface.
When I ran my test again, I got the same results.

If you monitor queue, do you see the traffic? This is made to limit upload, and if you want to limit download, use the interface which is connected to your lan (port 5 on your RB711 I would say) and be sure to put correct bandwidth limit according to capacity of your uplink. First remove all old mangle rules and queue tree.

Thanks,

I’ll play around with the interfaces for a while.

Hi All ,

If you use QoS , and You have on WAN DLS line.. it isn´t good.. Small range

Would you mind elaborating this statement?

In our normal understandment QoS + bandwidth control isn’t working as it should. How it’s working on mikrotik is the big question, I can’t reach logic of the developers on it. BTW, QoS alone working well. PCQ alone working well too, but together they doesn’t work, PCQ overrides all.

We control bandwidth on NAS-es (hotspot and PPPoE dynamically generated queues) and QoS on our main router (ASBR).
