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.

Single Network Interface

  1. Expand the Advanced Options section.

  2. Expand the Networking section.

  1. Under Network Interfaces, expand the default network interface.

  1. Expand the Network dropdown and select the VPC to use for the interface.

  2. Select the subnet that you want to use for your interface.

  1. It is recommended that you have a static IP address for the LAN1 interface. To reserve a static address, select Reserve STATIC INTERNAL IP ADDRESS from the Primary internal IPv4 dropdown.

  1. In the dialog window, enter a Name for the IP reservation.

  2. Under Static IP address, you can leave it set to Assign automatically or choose an IP address if desired.

  3. Click RESERVE.

  1. 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.

  1. In the Reserve IP dialog, enter a name for the reservation.

  2. Select a Network Service Tier.

  3. Click RESERVE.

  1. Click Done.

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.

  1. Expand the Network dropdown and select the VPC to use for the interface.

  2. Select the subnet that you want to use for your interface.

  3. 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.

  1. Click Done.

  1. Click Add network interface.

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

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

  1. It is recommended that you have a static IP address for the LAN1 interface. To reserve a static address, select Reserve static internal IP address from the Primary internal IP dropdown.

  1. In the dialog window, enter a Name for the IP reservation.

  2. Under Static IP address, you can leave it set to Assign automatically or choose an IP address if desired.

  3. Click RESERVE.

  1. Select RESERVE STATIC EXTERNAL IP ADDRESS from the External IPv4 address  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.

  1. In the Reserve IP dialog, enter a name for the reservation.

  2. Click RESERVE.

  1. Click Done for the new (LAN1) Network Interface.

You should now have two network interfaces for the VM, as shown below.
