Здравствуйте. Не могу разобрать в чем проблема. Есть сеть. Адреса клиенты получают по DHCP. Все как бы работает, но некоторые машины не получают адресс. клиент шлет DHCPDISCOVER, сервер отвечает DHCPOFFER и на этом все заканчиваеться. Но если подключить машину к сети например через wifi-роутер, то она нормально получает ip от wifi-роутера.
Лог dhcp на сервере
