Só descobri esse problema recentemente, aparentemente todas as minhas VMs do Ubuntu pararam de acessar a Internet. O host é o Windows 10, conectado via Ethernet ou WiFi, VMware Workstation 12.5.6, a configuração de rede no VMware é NAT. Minhas VMs Ubuntu precisam de um endereço estático, não consigo usar DHCP, aqui está a saída do ifconfig:

and this is the content of /etc/network/interfaces:
# The primary network interface
auto ens33
iface ens33 inet static

netmask 255.255.255.0

auto lo
iface lo inet loopback
Tentei fazer ping em 8.8.8.8, o host de destino está inacessível. Mais alguma coisa que eu possa verificar?
