How to control traffic on a Linux gateway?

Question

System administration

Hello fellow experts! Need advice.
The situation is this - there are 3 families who take the Internet via Wi-Fi. There is 1 physical channel, which is not possible to reach them due to many restrictions.
The channel comes to me on my working machine on which the bootloader with xfce is running, I work on it + I have a backup storage and a local file storage there. I have to distribute the Internet to my neighbors via Wi-Fi, which catches perfectly. A cursory search turned up webmin / ajenty - but I never found in the documentation that they can cut traffic to those who exceed daily quotas.
The question arose - how to control traffic on such a gateway? Maybe there are some kind of graphical web muzzles, so that you can manage and have a quick look? What do you guys recommend? It is necessary to cut traffic, by the hour, and by clients (in case of exceeding the quota).

Answer 1

raise pfSense in virtual machine

Answer 2

squid.

Answer 3

There is a commercial solution of Kerio Control, if you search you can find a working version without restrictions. It is configured as a gateway on a separate Linux server, there are many settings, including traffic quotas, speed limits, port forwarding and blocking, and much more. If you have not previously encountered such settings, it will be difficult without knowledge of the principles of network operation and an understanding of what you need. Most settings work by default.
upd:
Try it, they have a demo. https://control.demo.kerio.com:4081/admin/ Installation

In general, separate proxies, like pfSense or squid (which is even cooler because even https when building with libreSSL filters) - anything. I am for pfSense, since it is designed for this out of the box, that's just a computer, in this case, with a virtual machine in which the filterer must work 24/7 to limit and monitor traffic constantly
