Create the Virtual Networks

Updated Sep 15, 2023 ·

Overview

In VirtualBox, you will need to create the networks that will be used by the nodes.

VirtualBox Network Type	Network Name	Purpose / Network Type	CIDR / Address	DHCP
Host-Only Adapter	ManagementNetwork	Management (Controller ↔ Nodes)	10.0.0.0/24	Disabled
NAT Network	ProviderNetwork	Provider / VM traffic	10.10.10.0/24	Disabled (manual IPs optional)
NAT Network	Internet	Internet access / Updates	10.0.2.0/24	Enabled

To create the networks, go to Tools → Network → NAT Network.

Host-Only Adapter (Management Network)

Note: You cannot rename Host-Only adapters in VirtualBox on Windows. VirtualBox does not allow renaming in the GUI, because it links directly to a network interface in Windows.

1. Click + to create a new host-only adapter.

2. Select the adapter → click Edit:

   • IPv4 Address: 10.0.0.1
   • IPv4 Network Mask: 255.255.255.0
   • DHCP: Disabled (we’ll assign static IPs for the VMs)

3. Click Apply to save.

NAT Network (Provider Network)

1. Click + to create a new NAT network.

2. Click the Edit (gear icon) and update based on the table above.

3. Click Apply to save.
