1- As shown in the picture below, we enter the queue part of our Mikrotik device, where we limit the bandwidth of our users.
2- Here, as shown in the picture above, we press the + button, a window appears as follows.
As the picture also appears, we have a user called the Trial and we limit the Internet to 25MB. We have limited both Upload and Download to 20MB. In the Target section, if we give a fixed IP to our user, we limit it via IP. In other words, the user comes to the Internet where the wan leg is coming, whichever is on the internet we choose it.
3- Finally, we set the limits from Advanced to 25MB again as shown below.
