This article shows you how to use Virtual WAN to connect to your resources in Azure through a Network Virtual Appliance (NVA) in Azure. This type of connection requires a VPN device located on-premises that has an externally facing public IP address assigned to it. For more information about Virtual WAN, see What is Virtual WAN?
The steps in this article help you create a Barracuda CloudGen WAN Network Virtual Appliance in the Virtual WAN hub. To complete this exercise, you must have a Barracuda Cloud Premise Device (CPE) and a license for the Barracuda CloudGen WAN appliance that you deploy into the hub before you begin.
For deployment documentation of Cisco SD-WAN within Azure Virtual WAN, see Cisco Cloud OnRamp for Multi-Cloud.
For deployment documentation of VMware SD-WAN within Azure Virtual WAN, see Deployment Guide for VMware SD-WAN in Virtual WAN Hub
Verify that you've met the following criteria before beginning your configuration:
-
Obtain a license for your Barracuda CloudGen WAN gateway. To learn more about how to do this, see the Barracuda CloudGen WAN Documentation
-
You have a virtual network that you want to connect to. Verify that none of the subnets of your on-premises networks overlap with the virtual networks that you want to connect to. To create a virtual network in the Azure portal, see the Quickstart.
-
Your virtual network doesn't have any virtual network gateways. If your virtual network has a gateway (either VPN or ExpressRoute), you must remove all gateways. This configuration requires that virtual networks are connected instead, to the Virtual WAN hub gateway.
-
Obtain an IP address range for your hub region. The hub is a virtual network that is created and used by Virtual WAN. The address range that you specify for the hub can't overlap with any of your existing virtual networks that you connect to. It also can't overlap with your address ranges that you connect to your on-premises sites. If you're unfamiliar with the IP address ranges located in your on-premises network configuration, coordinate with someone who can provide those details for you.
-
If you don't have an Azure subscription, create a free account.
[!INCLUDE Create virtual WAN]
Create a virtual hub by filling out the Basics tab to create an empty virtual hub (a virtual hub that doesn't contain any gateways).
[!INCLUDE Create a virtual hub]
In this step, you'll create a Network Virtual Appliance in the hub. The procedure for each NVA will be different for each NVA partner's product. For this example, we're creating a Barracuda CloudGen WAN gateway.
-
Locate the Virtual WAN hub you created in the previous step and open it.

-
Find the Network Virtual Appliance tile and select the Create link.
-
On the Network Virtual Appliance page, from the dropdown, select Barracuda CloudGen WAN, then select the Create button and Leave. This takes you to the Azure Marketplace offer for the Barracuda CloudGen WAN gateway.
-
Read the terms, select Get it now, then click Continue when you're ready. The page will automatically change to the page for the Barracuda CloudGen WAN Gateway. Select Create to open the Basics page for gateway settings.

-
On the Create Barracuda CloudGen WAN Gateway Basics page, provide the following information:
- Subscription - Choose the subscription you used to deploy the Virtual WAN and hub.
- Resource Group - Choose the same Resource Group you used to deploy the Virtual WAN and hub.
- Region - Choose the same Region in which your Virtual hub resource is located.
- Application Name - The Barracuda NextGen WAN is a Managed Application. Choose a name that makes it easy to identify this resource, as this is what it will be called when it appears in your subscription.
- Managed Resource Group - This is the name of the Managed Resource Group in which Barracuda will deploy resources that are managed by them. The name should be pre-populated for this.
-
Select Next: CloudGen WAN gateway to open the Create Barracuda CloudGen WAN Gateway page.

-
On the Create Barracuda CloudGen WAN Gateway page, provide the following information:
- Virtual WAN Hub - The Virtual WAN hub you want to deploy this NVA into.
- NVA Infrastructure Units - Indicate the number of NVA Infrastructure Units you want to deploy this NVA with. Choose the amount of aggregate bandwidth capacity you want to provide across all of the branch sites that will be connecting to this hub through this NVA.
- Token - Barracuda requires that you provide an authentication token here in order to identify yourself as a registered user of this product. You'll need to obtain this from Barracuda.
-
Select the Review and Create button to proceed.
-
On this page, you'll be asked to accept the terms of the Co-Admin Access agreement. This is standard with Managed Applications where the Publisher will have access to some resources in this deployment. Check the I agree to the terms and conditions above box, and then select Create.
In this section, you create a connection between your hub and VNet.
