Different limits for Local/Overseas traffic for 3 bandwitch rates using pcq and queue tree

From MikroTik Wiki

1. Introduction

Let's consider the scenario where you want to apply different limits for many users to Local and Overseas traffic and don`t want to load cpu with a lot of simple queues and want sell 3 different bandwidth rates.
12/6 Mbps Latvian Traffic 1Mbps/512Kbps Overseas traffic
6/3 Mbps Latvian Traffic 512kbps/256Kbps Overseas traffic
4/2 Mbps Latvian Traffic 256Kbps/128Kbps Overseas traffic
We will limit the data rate for the Local country traffic and Overseas traffic using Queue Trees. In this scenario, the local country is Latvia. A list of all Latvian subnets is located at

3. Explanation

In /ip firewall address-list we created 3 lists for bandwidth profiles and a list named Latvia for Latvian subnets. In /ip firewall mangle we created address-list-based packet marks for use with bandwidth profiles. All IPs which are not included in any address list will fall through to secondary bandwidth profile rates. In /queue types we created pcq types for bandwidth profiles. In /queue tree we created rules with Local/Overseas packet marks and queue types for bandwidth profiles.
Now, a customer with an IP of will have 1 profile rate, a customer with an IP will have 2 profile rates, a client with IP have 3 profile rates, and all others will have 2 bandwidth rates; so all traffic will be limited and your cpu power will be free for other tasks.

Important note

This setup will work correctly if local network is not masqueraded. If masquerade is used then the parent for all upload queues must be 'global-out' instead of 'public'. The reason for this is that the pcq_upload classifier is source address. In case of masquerading, the source address is changed to public IP address. If a queue is set to 'public', interface pcq will think that all packets are coming from one source ( public IP ). PCQ must see the source address before masquerading occurs; according to the packet flow diagram from the manual, 'global-out' is before 'src-nat'.
