Доброго времени суток!
Внезапно перестало работать VPN соединение по протоколу PPTP.
Схема такова: В офисе сидит народ, который ходит через керио в интернеты, всё работает всё ништяк.
Некоторые работники должны использовать впн соеденение для подключения к удалённому серверу. При попытке подключения стала возникать ошибка 806 и жалуется на GRE протокол.
Но если подключится напрямую к проводу от провайдера, соединение работает и никаких ошибок не возникает.
в логе следующая лабуда:
