Стоит последняя декабрьская прошивка за 2010 год
Провайдер Beeline, проблема появляется и на PPTP и на L2TP. Напрямую без роутера все работает

Было все нормально но где-то 2 недели назад (скорее всего после очередного обновления Steam) стал отключаться интернет именно в момент подключения к игровому серверу в L4D2, какому не важно.
CSS играется нормально, Steam тоже работает, но стоит в игре L4D2 начать подключаться - disconnect, отключается весь интернет, горит желтым индикатор, браузер не показывает сайты, не работает cmd ping и т.д.
Через пол минуты сам переподключается, но стоит начать играть и опять...

Опытным путем выяснил что нужно убрать галку с IPSec в настройках Файерволла, причем не важно, используется ли PPTP или L2TP -
тогда все работает нормально. Раньше галка стояла но проблемы не было.

Хотя нет - не помогает - стало отваливатся опять - честно говоря не знаю что это может быть, видимо игра при коннекте к серверам посылает какие-то особые кадры.

Что творится в логах?

Вот логи - я их очистил, затем поставил галки на всех пунктах и запустил игру.
К 2 серверам присоединился нормально - затем сделал Steam аккаунт online (появляется список друзей кто в сети) и зашел на сервак - опять disconnect
Disconnect по часам на 21.20.37 (зависла графика в игре и через некоторое время выкинуло)

mtu наверное в настройках соединения стоит 1400?
если так, поставьте 1280.
вообще по логам мне лично кажется что у вас плохой кабель до провайдера.

нет у меня 1280 стоит, как рекомендовали где-то здесь на форуме, с 1400 l2tp вообще не работает, постоянно падает.

Еще раз повторюсь- без роутера, напрямую, все работает, если во время игры к роутеру подключено 2 компьютера то падает интернет на обоих машинах.

Я не играю, но тоже имею проблему. Роутер на последней прошивке теряет соединение с чем либо по WAN.
Соединение статическое. Лечится перезагрузкой роутера.
Что делать чтобы этого больше не происходило.
Сколько времени проходит между отваливанием связи сказать не могу.
