Certificate-based Point to Site Azure VPN through Intune

P2S VPN through Intune header

As the business world becomes increasingly mobile, cloud services are becoming even more attractive. But what if, as is often the case, there are still dependencies on an enterprise network - on Azure, for example? The solution is obvious: a point-to-site VPN ensures communication for mobile workers. In this how-to post, I discuss how a certificate-based point-to-site VPN to an Azure VPN gateway can be automatically rolled out to mobile clients through Intune. I also discuss how certificates can be automatically issued and renewed by a Certificate Authority in combination with Intune.

ARM template deployment – Hub and Spoke with Bastion

ARM Template Hub and Spoke with Bastion

With an Azure Resource Manager (ARM) template, you can create a specific infrastructure on Azure with the click of a button. The template defines the infrastructure as code and Azure is thereby told the target state of the resources. I have created such a template and published it via Github. The ARM template deployment includes a hub and spoke network topology with a central Azure bastion for secure access to VMs. This post shows you step by step how to use the template for yourself.

Use Azure Bastion with VNet peering

Azure Bastion with VNet peering

The Microsoft PaaS "Azure Bastion" is a popular service to make your Azure networks more secure. However, until now there was a drastic limit. Azure Bastion could only be used in the same VNet. VMs in a peered network could not be accessed via Bastion. This circumstance pushes up the costs, because with a hub-and-spoke topology you have to place a bastion in each VNet. But these times are over. Use Azure Bastion with VNet peering (since 05.11.2020 in preview).

Azure Bastion - Secure access to Azure VMs

The work forms "home office", "remote work" or even "work anywhere" are becoming increasingly important, especially in recent months. This change affects not only users, but also IT staff and system administrators. However, I am often confronted with mistrust and security concerns when dealing with such issues. This is where Azure Bastion comes into play. Bastion not only enables "work anywhere" for system administrators, but also provides increased security and secure access to your Azure VMs without the need for a VPN!

Azure Bastion Planning and Implementation

Azure Bastion is an Azure service that allows you to access your Azure VMs securely and centrally via the web portal. This allows you to enable your system administrators and system specialists to "work anywhere" without any security concerns. In this article I will not focus on the service itself, but rather on the steps necessary to plan and implement Azure Bastion.
