Доброго времени суток.
Имеется маршрутизатор на Debian Squeeze (2.6.32-5-686) с тремя интерфейсами.
Первый (eth0) - смотрит в сторону провайдера, второй (eth1) и беспроводная карточка в режиме Ad-hoc (wlan0) объеденены в мост (br0) и смотрят в локальную сеть.
На маршрутизаторе на инт. br0 поднят DHCP-сервер. При подключении компа с Win7 к eth0 все работает прекрасно, параметры сети принимаются с dhcp-сервера. При подключении к беспроводной карточке - эффекта ноль.

Т.е. запросы на получение айпишника и сетевых параметров приходят, но тупо виндой игнорятся.

В syslog'е аналогичная информация:

Кто нибудь сталкивался?

UPD: Если вручную выставить айпишник на ноуте, вывод пингов на 192.168.50.50 показывает, что заданный узел недоступен. Хотя tshark также показывает наличие сетевой активности.
