Всем доброго дня
Тема неоднократно поднимаемая, но очевидного решения или (банально) собственной ошибки - не наблюдаю, посему прошу подсказать

Пришло уведомление о том, что:
Dear Client,
I'm afraid we can't unblock your server until the problem is solved.
The problem still exist.
We have to see only this Mac on your switchport B4:2E:99:48:21:58
The Problem is that you use those not allowed MACs towards our Switch.

Т.е. мак адреса виртуальных машин иногда выходят в общую сеть
