My dear friend
Thank you for your answer.
3 or 4 connections.
Please suggest the easiest way.
I am not familiar with the local user manager and external radius.
Do I need additional hardware and software? (Except MikroTik router).
Please you explain step by step.
you could disable the PPPoE server at 7pm and enable it at 7am using the scheduler.
of course it will terminate ALL connections, so this easy solution is not possible when you want to have some connections (e.g. your own) excluded.
