How to Configure the Azure Connectivity Agent

  • Last updated on

The Azure Connectivity Agent allows you to use the Barracuda NG Firewall in the Azure Cloud as the default gateway for your Windows Server Azure VMs. The Connectivity Agent must be installed on all VMs in the VNET that initiate outgoing connections.

In this article:

Before you Begin

  • Deploy your Barracuda NG Firewall in the Azure Cloud. 
  • Deploy your Windows Server VMs in the same subnet(s) as the Barracuda NG Firewall. 
  • Create a PFX client certificate for each Windows Server VM. For more information, see How to Create Certificates with XCA
  • Copy the Azure Connectivity Agent and the client certificates to the Windows Server VM.
  • Create a Client-to-Site VPN on the Barracuda NG Firewall. Verify that it can be reached from the subnets where the Windows Server VMs are located. For more information, see Client-to-Site VPN.
  • (optional) Lock down the private subnets with Azure Network Security Groups to make sure outgoing traffic is sent through only the Barracuda NG Firewall.
