Yes, it is possible to modify and control the bandwidth for each client on a MikroTik device using various tools and features that RouterOS offers.

Two of the most common ways to do this are through Queue Tree and SimpleQueue.

These tools allow you to limit upload and download speeds for individual clients or groups of clients, which is useful for managing bandwidth allocation within a network and ensuring fair distribution of resources. Below I explain how you can do it:

Using Simple Queue

The Simple Queue tool is a quick and easy way to configure bandwidth limits for clients. Here I show you how:

1. Access your MikroTik device either through WinBox, WebFig, or SSH.
2. If you are using WinBox:
   • Go to Queues and then click Simple Queues.
   • click on the sign "+" to add a new queue.
   • In the countryside "name", assigns a name to identify the queue.
   • Use the fields “Target” to specify the client IP address or range of IP addresses to which you want to apply the limit.
   • En “Max Limit”, set the upload/download limits you want to impose.
3. Set limits of bandwidth as needed. You can specify different limits for uploading and downloading, as required for each client.
4. Save the changes. The new queue will begin throttling bandwidth for the specified client or clients according to the limits you have set.

Using Queue Tree

The Queue Tree allows for more granular and complex traffic management, ideal for more advanced configurations. Here you can create rules that apply to different types of traffic, interfaces, or even traffic priorities.

1. Create a package brand using Mangle on the firewall to identify traffic from certain clients or applications.
2. Go to Queue Tree and configure a new queue that uses the packet brand as a criterion.
3. Set limits specific bandwidth for this queue.

Considerations

• Priorization: In addition to limiting bandwidth, you can also assign priorities to different queues to better manage critical traffic.
• Structural: MikroTik provides tools to monitor traffic and queue performance, allowing you to adjust bandwidth policies as necessary.

Correctly configuring bandwidth for each client can help optimize the end-user experience, avoid network congestion, and ensure fair and equitable use of available network resources.
