Bandwidth limitation on mikrotik

RouterOS Beginner Basics

Hi Guys

I need help in configuring bandwidth controller on mikrotik. Following is my setup.

I have 20, 1mbps customers and total maximum bandwidth allowed at present is 3 Mbps between 20 customers.

My connection sharing ratio is 1:10

To share the speed equally between users i have following setup.

1 - USER AUTHENTICATES THROUGH PPPOE
2 - I CLASIFY THE TRAFFIC AND MARK THE PACKETS FOR THE TYPE OF BROADBAND CONNECTION
3 - I HAVE CREATED PCQ QUEUES FOR TYPE OF PLAN TO SHARE THE CONNECTION EQUALY BETWEEN USERS
4 - FINALLY I HAVE CREATED QUEUE TREE FOR UPLOAD and DOWNLOAD LIMITATIONS, WITH-LIMIT AT - 2Mbps AND MAX-LIMIT - 3Mbps

What I want to achieve is that each customer should not exceed 1 Mbps customer even though there is max of 3Mbps is available. Currently if there is only one user active then particular user will take all the available bandwidth (i.e. 3Mbps). This creates the problem for me as if there are more customers online then speed will be less and customers are complaining that they used to get 3Mbps and now its less. What i want to achieve is that each user should not exceed more than 1 Mbps speed even though more bandwidth is available.

Can anyone please point me to right direction?

Set the limit per customer in the PCQ using the Rate: setting

Hope that helps

Tried that but it doesn’t seem to be working.

i set pcq-rate as 1024k, but still my users are able to download upto 3mbps

i would suggest you set a pfifo queue (the default queue) for every customer (20 queues are not that much for a router) with max-limit 1Mbps, the parent of the 20 queues should have a max limit of 3Mbps or even better (3*0.90)Mbps just to be sure that packets don’t get queued in your ISP’s router. I don’t encourage using limit-at for the parent queue.
and this also means you have to mark the traffic of each client (20 or 40 rules in mangle chain, also no big deal for the router)

I am running ISP so users will not be static so above option is not valid for me.

Following is my setup however PCQ-RATE option doesn’t seem to be working. If one user is online he is talking all (3Mbps) bandwidth. What I want to achieve is that maximum bandwidth per user should not exceed 1Mbps.

I am running ISP and my customers are authenticating through PPPoE. They will get private IP in the range of 172.20.8.0/22 and access the internet through NAT. I have also other users in different ip range, different broadband plan, however to narrow down the problem I am pasting the config for one type of customer only.

/ip firewall mangle

chain=prerouting action=mark-connection new-connection-mark=1024-Connection passthrough=yes src-address=172.20.8.0/22
chain=prerouting action=mark-packet new-packet-mark=1024Users passthrough=yes connection-mark=1024-Connection

/queue type

name=“1024-Down” kind=pcq pcq-rate=1024k pcq-limit=50 pcq-classifier=dst-address pcq-total-limit=2000 pcq-burst-rate=0
pcq-burst-threshold=0 pcq-burst-time=10s pcq-src-address-mask=32 pcq-dst-address-mask=32 pcq-src-address6-mask=128
pcq-dst-address6-mask=128
name=“1024-Up” kind=pcq pcq-rate=1024k pcq-limit=50 pcq-classifier=src-address pcq-total-limit=2000 pcq-burst-rate=0 pcq-burst-threshold=>
pcq-burst-time=10s pcq-src-address-mask=32 pcq-dst-address-mask=32 pcq-src-address6-mask=128 pcq-dst-address6-mask=128

/queue tree …ether1 - connected to WAN, ether2 connected to LAN

name=“QUPLOAD” parent=ether1 packet-mark=“” limit-at=0 priority=8 max-limit=10240k burst-limit=0 burst-threshold=0 burst-time=0s
name=“QDOWNLOAD” parent=ether2 packet-mark=“” limit-at=0 priority=8 max-limit=10240k burst-limit=0 burst-threshold=0 burst-time=0s
name=“1MbpsDownload” parent=QDOWNLOAD packet-mark=1024Users limit-at=0 queue=1024-Down priority=8 max-limit=3076k burst-limit=0 burst-threshold=0 burst-time=0s
name=“1MbpsUpload” parent=QUPLOAD packet-mark=1024Users limit-at=0 queue=1024-Up priority=8 max-limit=3076k burst-limit=0
burst-threshold=0 burst-time=0s



Any ideas what’s wrong in the config?

users are not connected to ether2, users are connected to pppoe interfaces, one interface per user :slight_smile: so…
/ip firewall mangle
add chain=forward action=mark-packet new-packet-mark=1024-upload src-address=172.20.8.0/22
add chain=forward action=mark-packet new-packet-mark=1024-download dst-address=172.20.8.0/22

/queue tree
add name=“1MbpsDownload” parent=global-out packet-mark=1024-download queue=1024-Down max-limit=3076k
add name=“1MbpsUpload” parent=global-out packet-mark=1024-upload queue=1024-Up max-limit=3076k
