The Network Manager tool in VirtualBox Manager enables you to create, delete, and configure the following types of networks used by Oracle VM VirtualBox:
Host-only networks. See Section 6.11.1, “Host-Only Networks Tab”.
NAT networks. See Section 6.11.2, “NAT Networks Tab”.
Cloud networks. See Section 6.11.3, “Cloud Networks Tab”.
To display the Network Manager, go to the global Tools menu and click Network.
The Host-Only Networks tab in Network Manager lists all host-only networks that are currently in use.
Click Create to add a new host-only network to the list.
Click Remove to remove a host-only network from the list.
Click Properties to show or hide settings for the selected host-only network.
To configure a host-only network, select the network name in the Name field and do the following:
Use the Adapter tab to configure the network adapter for the host-only network.
Use the DHCP Server tab to configure settings for the DHCP server used by the host-only network. The DHCP server is built into Oracle VM VirtualBox and manages IP addresses for the network automatically.
The NAT Networks tab in Network Manager lists all NAT networks that are currently in use.
Click Create to add a new NAT network to the list.
Click Remove to remove a NAT network from the list.
Click Properties to show or hide settings for the selected NAT network.
To configure a NAT network, select the network name in the Name field and do the following:
Use the General Options tab to configure the network settings used by the NAT network. For example, the network address and mask of the NAT service interface.
Use the Port Forwarding tab to configure port forwarding rules used by the NAT network.
The Cloud Networks tab in Network Manager lists all cloud networks that are currently in use.
Click Create to add a new cloud network to the list.
Click Remove to remove a cloud network from the list.
Click Properties to show or hide settings for the selected cloud network.
To configure a cloud network, select the network name in the Name field and specify the following:
Name: The name used for the cloud network.
Provider: The cloud service provider, such as Oracle Cloud Infrastructure.
Profile: The cloud profile used to connect to the cloud network.
ID: The OCID for the cloud tunneling network. Click the Network icon to view the subnets on Oracle Cloud Infrastructure that are available for tunneling traffic.
See Section 1.16.10, “Using a Cloud Network” for details of how you can use the VBoxManage cloud command to create and configure a virtual cloud network (VCN) on Oracle Cloud Infrastructure.
