DHCP-сервер не отвечает на запрос DHCPDISCOVER [закрыто]

Я использую дистрибутив linux security onion в качестве виртуальной машины на хосте windows 7 через virtual box. Эта виртуальная машина не может получить IP-адрес от сервера DHCP. Эта проблема является результатом создания внутренней сети в виртуальной коробке. С тех пор я попробовал bridged, NAT и internal networking, это просто не будет работать.
