I use VirtualBox for a lot of development on my laptop, and as such I do not always have Internet access; and not always connected via ethernet. For the +primary network interface+, I use a *Host-only* network type to connect with the VMs when disconnected from the Internet; however I also need Internet access when I am connected via WiFi or ethernet. To do this +just add a second network interface to the VM+ in use and make sure to sure set the network type to *NAT*. h2. VirtualBox GUI In this example the host-only network is called _vboxnet0_, and I configured the network to another network instead of the default _192.168.56.0_ network. * Configure the Host-only network in +VirtualBox -> File -> Preferences -> Network -> Host-only Networks+ and click *[+] Add host-only network*. Click *OK* when finished. * Configure the primary network interface for the VM by going to +Settings -> Network Adapter 1+ and change +Attached to+ to *Host-only Adapter*, then change the +Name+ to *vboxnet0*. * Configure the secondary network interface for the VM by going to +Settings -> Network Adapter 2+ and change +Attached to+ to NAT*. * Click *OK* when finished. Now the VM will have two interfaces; one for the connection to the host machine and one to connect to the Internet using NAT. h2. VBoxManage In this example the host-only network is called _vboxnet1_, and I configured the network to another network instead of the default _192.168.56.0_ network. * Create the Host-only network interface: VBoxManage hostonlyif create #* _Example output_ <pre> 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Interface 'vboxnet1' was successfully created </pre> * Set the host-only network interface IP address: <pre> VBoxManage hostonlyif ipconfig vboxnet1 --ip 192.168.88.1 </pre> * (Optional) Setup a DHCP server for the host-only network: <pre> VBoxManage dhcpserver add --netname vboxnet1 --ip 192.168.88.1 --netmask 255.255.255.0 --lowerip 192.168.88.100 --upperip 192.168.88.150 --enable </pre> * Configure the primary network interface for the VM <pre> VBoxManage modifyvm "ExampleVM" --nic1 hostonly --hostonlyadapter1 vboxnet1 </pre> * Configure the secondary network interface for the VM <pre> VBoxManage modifyvm "ExampleVM" --nic2 nat </pre> h2.
