> DSL модем неверно получает гейт
    Как такое могло получиться? DSL модем TP-Link TD8810 в режиме роутера получает гейт из внутренней сети провайдера. При этом праймари днс определяется верно. vpi/vci прова - 0/35. Mtu стоит по дефолту на самом модеме.

    При диагностике получаю следующие ошибки:

    Test ATM OAM F5 segment ping: FAIL
    Test ATM OAM F5 end-to-end ping: FAIL
    Ping default gateway: FAIL

    Естественно нет не работает. Саппорт прова ничего вразумительного объяснить не смог, ограничился - "У вас проблемы на линии".
      на чем сетка? pppoe, ipoe, глянь и скинь сюды логи мопеда

          сервак ипку отдал и коннект поднял, но не отдал дефолтный гетвей и днс, если есть под рукой для теста другой мопед, попробуй поднять коннект на нем, если таже хрень - терзай прова

            SPT=1123 DPT=445

            у тебя чтото ломится на 445-й порт, возможно вирусня, если пров злой и не просто тупо дропает "нехорошие" пакетики, он могет дропать коннект, хотя это маловероянтно
              mtu сколько выставить?
                я всегда ставлю дефолтом, хз как у вас там в сетке, спроси у лучше саппорта
                  Второй модем требует его проставить. Саппорт прова не знает, что это такое.

                    :hang:
                    Глянь какой стоит в 8810 - поставь такой же
                    ЗЫ. У мну 8817 - стоит 1480
                      Попробовал второй модем TP-Link 108M. mtu по дефолту там 1492

                      Тут еще лучше ситуация

                        На эту лапшу инет вешаешь первый раз, или до этого инет был?
                          До этого другой пров был. Только у него vpi/vci 8/35 было. Но инет работал, не без глюков конечно, но работал и соединение с ррр сервером устанавливалось без ошибок.

                          ЗЫ: модем до сих пор в шоке

                              Спасибо, уже пакую. Посмотрим, что они скажут.
                                Потом отпишись, интересно чем дело закончится :)
