Доброго времени суток.
Комп с Gentoo на борту (назовём его хост), подключен к интернету через роутер (внутренний адрес роутера 192.168.1.1, адрес хоста - 192.168.1.2). На хосте раздаётся локалка, а также стоит несколько гостей в виртуалке (используется qemu, libvirt, virt-manager).

Интерфейс enp2s0 смотрит в интернет (через роутер), enp4s0u1 смотрит в локалку, virbr[0,1,2,3] - виртуальные мосты, обслуживающие гостей в виртуалке.
Конфиг сети:
# cat /etc/conf.d/net
config_enp2s0="dhcp"
config_enp4s0u1="172.16.0.1/24"
modules_enp4s0u1="!ifplugd"
Установлен dnsmasq, задачей которого является обслуживание enp4s0u1
cat /etc/dnsmasq.conf
resolv-file=/etc/resolv.conf
dhcp-host=25:1c:2a:03:e3:41,172.16.0.2,24h
bind-interfaces
except-interface=virbr0
except-interface=virbr1
except-interface=virbr2
except-interface=virbr3
Проблема в том, что адрес 172.16.0.2 не присваиваетя подключаемому проводом ноуту (MAC правильный).

Подскажите в чём проблема.
Заранее благодарен.
ps Виртуальные мосты работают нормально, настраивались через virt-manager автономно.
