Where I live, I share internet with three other roommates spanning two floors. I have a Mikrotik Routerboard without any sort of built in wireless and I have a Netgear R7000 that I turned into just an access point. This is what I would like to accomplish:

• Group devices by each owner (roommate).
• Setup some type of hotspot system or timed internet usage that I could charge by the month.
• An easy way to turn of groups of devices owned by the roommate in the event of failure to pay.

I plan on building a web application that is hosted locally to do all of the payment processing. The website would be programmed to text me when a payment is missed 24 hours after the due date. I would like to forward all web traffic for the devices of the delinquent payer to this locally hosted web server for them to pay me.

Should I be looking at some sort of Radius solution or there a simple way to turn off / forward all web traffic for disabled devices?

Thank you in advance!

Using the basic setup for a hotspot will allow multiple users. You can download the Winbox program for
Windows and manage the list of users allowed on your network. If your roomate does not pay, remove his/her
profile. However, he/she can ask your other roomate for their credentials, bypassing your lockout.

So......
Under IP->Pool create a set of pools for each roomate. (IE: Tom: 192.168.88.10 - 192.168.88.19 Harry: 192.168.88.20 - 192.168.88.29)
Under IP ->Hotspot->User Profiles create a profile for each roomate and for Address Pool select the pool for that roomate.
Set Shared Users to the number of IP addresses for that roomate in the pool. (IE 10 for above example)
This allows a limit on the number of devices for that signin.

After a week or so, when your roommates have used their sigins, Under IP->DHCP Server->Leases and make the
active IP addresses static. That way you have the mac address stored in case they try to bypass your lockout
by using a borrowed signin.
.
If needed reduce the active pool down to only allow the real number of paid devices.
