  1. ничего там нет, проверял,

     

    есть варианты как запретить фрагментацию пакетов ?:) или df бит все виндовые машины ставят по умолчанию, например tcp adj mss?

  2. Всем привет, имеем на одном конце VTI тунеля 2811 с aim vpn EPII plus, на другом 1841.

     

    Конфиг с 1841

    Это нормально? При full duplex 16491000 бит/с , это я еще на 50Mbit не разогнал )

     

     

    По поводу Qos ... можно и GRE шейпить, но мне удобнее мой вариант.

     

     

    2811 грузится до 60% при наличии только ЭТОГО трафа.

     

  3. Суть впринципи проста, надо удалить эту группу, но далее изменить на интерфейсе парметр pppoe enable group global на pppoe enable... а этого не происходит ).... он снова ставит pppoe enable group global. А это уже косяк )

  4. ага, словил ) ... bba-group убрал и не работает....

    Где тут строчка, которая заставляет думать 1841 что он сервер ? Мешает работе других клиентов типа d-link, они при поиске сервера считают её за сервер...

     

    Подскажите как исправить

    спасибо
