If you require bandwidth control in Dhcp Server leases, we can do it. We will have to create a static entry in leases, then click on the static entry and in the rate limit field enter the value of the limit. Doing this automatically generates a simple queue.

It can also be achieved by using Queue functionalities to control and limit network traffic. We explain how you can configure this step by step:

Configuring Queues for Bandwidth Limits

1. DHCP Server Configuration:
   • First, make sure your DHCP server on MikroTik is configured and working correctly. This includes having a defined IP address range that the DHCP server will assign to clients.
2. Creating Simple Queues:
   • To limit the bandwidth for a specific DHCP lease, you can create a Simple Queue. Each queue will allow you to control the maximum bandwidth for upload and download for a specific IP address.
   • Go to “Queues” and then to “Simple Queues” in the main menu of MikroTik RouterOS.
   • Click the button “+”/”Add” to create a new queue.
   • In the countryside "name", assigns an identifiable name to the queue.
   • In the countryside “Target”, enter the IP address of the DHCP lease to which you want to apply the bandwidth limit.
   • Defines the limits in “Max Limit” for the ascent and descent according to your needs.
3. Automation with Scripts:
   • To automate the assignment of bandwidth limits to each DHCP lease, you can write a script in RouterOS that dynamically associates a simple queue with each new IP address that the DHCP server assigns.
   • This script can be run every time a new lease is assigned or at regular intervals to check for changes to DHCP leases.
4. Using PCQ (Per Connection Queue):
   • If you want to implement a bandwidth policy that applies more generally to multiple users, consider using PCQ. This technique allows you to limit the bandwidth per connection equally among all active users.
   • Set PCQ to “Queue Types” and then use this configuration in the “Simple Queues” or “Queue Tree”.
5. Monitoring and Adjustments:
   • After setting up queues, it is important to monitor their effectiveness and make adjustments as necessary. MikroTik RouterOS provides tools to monitor traffic and queue performance in real time.

Implementing bandwidth limits through DHCP lease in MikroTik can be an effective way to manage network traffic and ensure equitable distribution of bandwidth among all users, thus improving the quality of service on the network.
