Infoblox vNIOS for GCP instances using NIOS version 8.6 and later can be deployed with one or two network interfaces. Instances deployed with a single network interface can be deployed into a standard VPC or a shared VPC. Older versions of NIOS require two network interfaces. Follow instructions in the appropriate subsection depending on the number of network interfaces and VPC type you will deploy.

> Macro (toc)

### **Single Network Interface**

1. Expand the **Advanced Options **section.
2. Expand the **Networking** section.

10. Select **RESERVE STATIC EXTERNAL IP ADDRESS** from the External IPv4 dropdown.

*Note: If you plan to connect to your vNIOS instance using VPN, Cloud Interconnect, or another private method, you may not need an External IP address.*

### **Two Network Interfaces**

1. Expand the **Advanced Options **section.
2. Expand the **Networking** section.
3. Under Network Interfaces, expand the default network interface.

*Note: This first network interface will be labeled as nic0 for the GCP VM instance. When deploying instances with two interfaces, this will be the MGMT interface in vNIOS.*

4. Expand the **Network** dropdown and select the VPC to use for the interface.
5. Select the subnet that you want to use for your interface.
6. For External IPv4 address, select **None**.

*Note: You can add an external IP for the MGMT interface if desired, but this is not commonly needed.*

7. Click **Done**.

*Note: This new network interface will be labeled as nic1 for the GCP VM instance. This will be the LAN1 interface in vNIOS.*

9. Select the VPC and subnet to use with this interface (this must be a different VPC than the one used with the MGMT interface).
