Как се защитавате от flood на микротика

[selianina]

Здравейте колеги, искам да попитам как се справяте с проблемните клиенти който имат вируси и затрудняват работата на микротиците.Какви методи използвате или филтрирате определени портове? Четох някъде из нета за Syn-protect но не намерих много информация пише че е за защита от flood някой ползвал ли го е до сега?
