Доброго времени суток.
Наличие данной проблемы заствляет меня потоянно перезагружаться в windows(
Итак топология (сразу скажу извращённая):

Есть мой laptop, который с по ip-sec тоннелю подключен к моей офисной сети из которой мне выдался адрес 10.33.251.7. Используется vpnclient --version 4.8.01 (0640). Тоннер работает нормально и внутренний трафик в том числе http обрабатывает. Посену надеюсь пока можно предположить, что проблема не в нём.
Далле есть GW to customer net, который имеет адрес 83.206.87.68 и глядит в сеть заказчика, в которую мне как раз и надо, а конкретно на сервер Apache, имеющий адрес 10.84.18.65. Для доступа к нему я испульзую ssh тоннель с Port Forwarding, с переадресацией портов 22 и 80. Команда
user@user-laptop:~$ sudo ssh -vvv -L 10.33.251.7:22:10.84.18.65:22 -L 10.33.251.7:80:10.84.18.65:80 login@83.206.87.68 -N
позволяет мне успешно пользоваться ssh, а вот с http у меня возникают траблы: загружается только чать страницы и далее браузер говорит waiting, причём как только я отсылаю запрос ssh соединений (если оно было открыто) становиться «односторонним»: я вижу, что происходит на сервер (top к примеру отображается) но не реагирует на клавиатуру, даже на ctrl-c. Ниже то, что я вижу в консоле с моими комментариями:


user@user-laptop:~$ sudo ssh -vvv -L 10.33.251.7:22:10.84.18.65:22 -L 10.33.251.7:80:10.84.18.65:80 login@83.206.87.68 -N
