Добрый день!
Неделю бьемся с проблемой - внезапно стали происходить разрывы PPTP соединений. Серверов несколько, наблюдается на всех. Не то чтоы повально, но у некоторых пользователях они периодически постоянно повторяются. При чем сеть работает отлично, до сервера ping не пропадает. Уже все мысли закончились.Вот снял лог tcpdump пользователя, который был подключен, работал и у него вдруг случился разрыв.
