 The Mac mini is attached to the Private Network, and you are returned to the **Private Networks** tab. The IPv4 and the IPv6 addresses for the Mac mini on the Private Network are displayed, along with the ID of the VLAN interface that was created.

+## How to configure the VLAN interface on your Mac mini for Private Networks
+
+You must configure the virtual network interface on each Mac mini you have attached to a Private Network. Traffic from the public internet and traffic from a Private Network will pass through the same network interface of the Mac mini. We must therefore separate the traffic by adding a VLAN interface.
+
+To configure the interface, you must connect to your Mac mini, either via SSH or the remote desktop and carry out the instructions given.
+
+### Via SSH and networksetup
+
+1. Make a note of your Mac mini's **VLAN ID**. You can view this in the Scaleway console, in the **Private Networks** tab of the Mac mini in question.
+2. [Connect to your Mac mini via SSH](/bare-metal/apple-silicon/how-to/connect-to-mac-mini-ssh/).
+3. Use the following command to bring up the interface. Ensure you replace `<VLAN_ID>` with the VLAN_ID from step one.
+    ```
+    sudo networksetup -createVLAN pn en0 <VLAN_ID>
+    ```
+4. Check that the interface has been brought up with the following command:
+    ```
+    sudo networksetup -listVLANs
+    ```
+    You should see a response similar to the following:
+    ```
+    VLAN User Defined Name: pn
+    Parent Device: en0
+    Device ("Hardware" Port): vlan0
+    Tag: 3548
+    ```
+
+No configuration is required for your Mac mini's IP address on the Private Network, as this is automatically managed by Scaleway DHCP. You can view the IP address in the Scaleway console, in the Mac mini's **Private Networks** tab.
+
+<Message type="tip">
+  If you have any issues with bringing up the VLAN interface or the IP address, the following commands may be helpful.
+
+  To delete the VLAN, so you can attempt re-creation;
+  ```
+  sudo networksetup -deleteVLAN pn en0 <VLAN_ID>
+  ```
+  To renew the DHCP lease:
+  ```
+  sudo ipconfig set en0 BOOTP && sudo ipconfig set en0 DHCP
+  ```
+</Message>
+
+### Via remote desktop
+
+1. Make a note of your Mac mini's **VLAN ID**. You can view this in the Scaleway console, in the **Private Networks** tab of the Mac mini in question.
+2. [Access the Mac mini's remote desktop](/bare-metal/apple-silicon/how-to/access-remote-desktop-mac-mini/).
+3. Go to **System Settings** > **Network**, then click **...v** and select **Manage Virtual Interfaces** from the menu that displays.
+    <Lightbox src="scaleway-m1-network.webp" />
+4. Click **+** > **New VLAN** to add a new virtual interface.
+    <Lightbox src="scaleway-m1-vlan.webp" />
+5. Enter a **VLAN name** of your choice, the VLAN ID from step 1 in the **Tag** field, and **Ethernet** as the interface. Click **Done**.
+
+The VLAN interface is created. You can check its status in the **Network** tab, and see its full details by clicking on it.

 ## How to view the resource's IP address
 
 When you attach a resource to a Private Network, it gets a private IPv4 address on that network (and also an IPv6 address, if supported by the resource). Private IPs are assigned from the CIDR block defined at the time of the Private Network's creation, either via auto-assignment or specification of a particular [reserved IP](/network/ipam/how-to/reserve-ip/).
