Limits users using NAT behind my Router

RouterOS General

Hi

Is there any way on ip firewall I can limit so the user won’t be able to share internet more than two mac address.
I was to limit them and allow only specific range of ip they can use to go on Internet.

Thanks
Miles

You can only allow certain address to use the internet, but if a user uses one of those addresses and performs NAT behind it… That as they say is that.

So if a user performs NAT behind a valid address you won’t see the MAC address of any device except the head end device. This is the nature of layer 3.
