имеется свежеустановленный арч на отдельный винт в virtualbox(.vbox)
в rc.conf interface=eth0

при запуске в виртуалбоксе по dhcp от виртуалбокса получает настройки и удачно их применяет
но при физическом запуске арча с винта, применяются все данные от реального dhcp кроме default gw

собственно, что не так?

Вы проверяли, DHCP действительно раздаёт адрес гейта?

проверил, в бунте nm его по dhcp получает и применяет

От рута:
Покажите вывод 
grep dhcpcd /var/log/daemon.log
а потом 
dhcpcd -k eth0
dhcpcd -d eth0

Видимо, ваш DHCP настроен или устроен как-то специфически, и передаёт гейт в особом формате, непонятном dhcpcd, зато передаёт кучу дополнительных роутов.

В убунте используется dhclient.
Попробуйте установить его, и запустить 
dhcpcd -k eth0
dhclient -v eth0

А я все же бы не логи смотрел (в первую очередь), а настройки DHCP сервера. Не корректность настроек DHCP-сервера, на мой взгяд, куда более очевидна чем возможность кривой работы клиента….
Покажите, пожалуйста, конфигурационный файл dhcpd.conf, если вы пользуетесь оным, а не чудом вроде dnsmasq

Ну вот и очевидная проблема - вы выдаете дополнительные маршруты для клиентов сетей MS, и для работающих по стандарту RFC, а основной маршрут закоменчен в настройках.
Разкоментируйте option routers и укажите нужный вам шлюз по умолчанию.

Gineaser, так задача то, выдавать каждому юзеру свой гейт, а некоторым вообще никакого, никакой проблемы
