Всем привет! Столкнулся с такой проблемой. Буду очень признателен за советы.
У клиента стоит микротик RB951Ui-2HnD, прошивка 6.48 (stable). Провайдер Ростелеком, подключение по PPPOE. Не открывается часть сайтов, например, рамблер (попалось под руку). Иногда не открывается gooogle.com, а вот google.ru открывается. DNS-сервера менял на публичные 8.8.8.8, 8.8.4.4. – не помогло, меняли MTU – не помогло. Все пингуется, все трассировки проходят, всё супер, но какая-то часть сайтов не открывается.
Если включить VPN в опере, то всё окей, работает, как часы.
Ростелеком говорит, что всё с их стороны работает.
Что может быть? Куда копать?
