Queue problem for PPPoE traffic originated from a routed subnet

Thu Oct 21, 2021 9:25 pm

Hello,
I've a strange problem in queueing some PPPoe traffic.

Situation:
- PPPoE server without fasttrack
- RB client that has the IP 100.65.0.10 assigned to PPPoE interface
- RB client that has the first usable IP of /30 assigned to a physical interface
- Public /30 routed to PPPoE
- Queue 30M download 10M upload

If I do a bandwidth test from client RB to an internet router I get 30/10 so the exac that I expect.
If I do a bandwidth test from an host that has the second usable address of the /30 to an internet router the upload queue works so 10M but the download queue does not match packets so it's ignored and I get unlimited bandwidth (50M in this case)

I had this issue and mikrotik support responded in an email i wrote to them.
When traffic goes inside a queue once it cannot pass again in single queues - so if lets say you have 2 queues for client A and B - the order is important.

If you have client A limited at 100/100 and talking to client B with a limit 50/20 then essentially client B will have 100/100 only when talking to A as it will hit the queue of A first essentially ignoring B's limits.

Hope this helps - there is no way to fix this with dynamic pppoe single queues.

CoMMyz it's not a problem of a client that talks to another queued client, but a client going to the internet, so there is only one queue.
To recap:
- Queue UP/DOWN for packet originated from the PPPoE assigned address works
- Queue UP for packet originated from the routed subnet to PPPoE works
- Queue DOWN for packet originated from the routed subnet to PPPoE NOT works

I think your best option is going to send copies of config / supout file to MT support
