I can get the setup I want by setting up two adapters on the vm. VirtualBox 4.2.12 Ubuntu 12.04 guest In VirtualBox > Preferences > Network, set up a host-only network. Mine is called vboxnet0, it is manually configured: ip 192.168.56.1 netmask 255.255.255.0 no dhcp Then, in the network settings for the virtual machine, set up two adapters: Adapter 1 host only, vboxnet0 Adapter2 NAT Boot the virtual machine and log in through the console VirtualBox provides. Run this to see your adapters: ls /sys/class/net In my case the adapters were named eth1 and eth2 (and lo, the loopback interface). Then, edit your network configuration. sudoedit /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback # Host-only interface auto eth1 iface eth1 inet static address 192.168.56.20 netmask 255.255.255.0 network 192.168.56.0 broadcast 192.168.56.255 # NAT interface auto eth2 iface eth2 inet dhcp Note that eth1 has no default gateway specified. eth2 will get a default gateway from dhcp.
