Client VPN connectivity for secure remote access by development and operations teams to cloud-based workloads that are provisioned on an Azure Virtual Network.
Before we can manage Azure resources via the Azure PowerShell module, we'll first need to authenticate. Authentication to Azure can be accomplished via management certificates, or via Azure Active Directory. Once we've authenticated to Azure, we'll next select the Azure subscription in which our Azure Virtual Network is provisioned.
Many organizations have more than one Azure subscription for different release stages dev, test, productionapplications or business units. After selecting the appropriate Azure subscription, we'll need to grab the subscription ID and the management certificate thumbprint we used when authenticating to Azure. Some organizations may have more than one Azure Virtual Network provisioned within their Azure subscription. Now, we can choose the VPN client certificate that's associated with the user that we wish to disable.
When initially provisioning VPN client certificates for your users, be sure to use a certificate naming convention that makes it easy to identify each certificate based on username. Also, be sure to save a copy of each certificate in a safe location so that you can easily access them later, if needed. When we call this API, we'll pass along the relevant values that we've collected above. After a user's VPN client certificate is revoked, if they should attempt to connect to the Point-to-Site VPN Gateway, their connection will not be successfully authenticated and they will receive the below error message.
In some cases, you may find that you need to later reinstate a revoked VPN client certificate. Luckily, we can use the same Azure API to reinstate certificates that were previously revoked by using the code snippet below. Skip to main content. Exit focus mode. Authenticate to Azure Before we can manage Azure resources via the Azure PowerShell module, we'll first need to authenticate. Select Azure Subscription Once we've authenticated to Azure, we'll next select the Azure subscription in which our Azure Virtual Network is provisioned.
I have configured the VPN in Azure and it is downloaded and extracted and the vpn client is installed successfully, however, when I run the client I received the following error:. A certificate could not be found that can be used with this Extensible Authentication Protocol.
Error UPDATE: I removed the existing certification in Azure's configuration and re-added back with the same FQDN name shown in local computer's certificates, I redownloaded the client, I removed the existing installed vpn client and re-installed the new one, I receive the same error message.
So it seems name is not the root cause? Add the self-signed certificate as a trusted certificate authority, Copy the new cert to Trusted Root Certificate Authorities. When you try to connect to an Azure virtual network by using the VPN client, except for exporting the root certificate public key. You generate a client certificate from the self-signed root certificate and then export and install the client certificate.
Configuring Azure Point-to-Site VPN with Windows 10
If the client certificate is not installed, authentication fails. You could follow this solution to fix this issue.
For more information about how to install the client certificate, see Generate and export certificates for point-to-site connections.
In rare circumstances you may find that this solution will only work for a short time usually failing the next time you reboot. In this case you may need to follow these additional steps. In case anyone runs into this issue at some stage, I had installed a new root cert that worked for 2 out of 3 VPN gateways fine.
The third kept giving a error even though the certs were correct and in the right place. Learn more.

Creating an Azure Client VPN (point-to-site)
Nancy Xiong Nancy Xiong This guide will demonstrate how to configure a point-to-site configuration within Azure, and how to deploy this out to users automatically via Group Policy. The virtual network will require a virtual network gateway to provide the functionality of configuring a point-to-site VPN connection.
If your resource group already contains a virtual network gateway, skip to step 3. Once the Virtual Network Gateway has been configured, you will see this displayed within your resource group. Click on this to open the blade for configuration. Go to Point-to-site configuration to begin the configuration. First, we shall need to generate certificates used for client authentication this is a self-signed root certificate which is imported into Azure, which then uses a child certificates for user authentication.
From a Windows 10 machine, run the following command in an elevated PowerShell window do not close the window :. Now that we have generated a root certificate on a Windows 10 machine, we need to make sure this is kept safe by exporting the certificate to a PFX file make note of the PFX password.
This command will have generated a child certificate on the Windows 10 machine, which now needs to be exported to a PFX file using the same process used in Step 5.
You should now have a folder with both the root and child certificates as a PFX file, with a text file containing the passwords for each certificate. Back in the Azure portal, paste the copied certificate text into the point-to-site configuration section of the Virtual network gateway.
Give this a useful name. Click on this and extract the downloaded zip file. This will configure the Azure VPN on your machine, whilst this is an easy method to connect to the Azure VPN it may not suit the client as this process requires manual interaction. For group policy we need to create the VPN using alternate methods. Now that we have configured the P2S settings with both root and child certificates generated for authentication, we now need to configure the client-side VPN, so users can connect from their machines.
To do this we shall deploy the child certificate via Group policy using a PowerShell script. Below is a step by step guide on how to configure this. In the previous step 8, we had a folder which contained both the root and child certificate, alongside a text file containing the passwords. Once you have adjusted the script accordingly, it should look something like this:. This process should now have created a group policy which runs the edited script to deploy the Azure VPN using the child certificate we created.A certificate could not be found that can be used with this Extensible Authentication Protocol
Michael Nelson Great write up! But I don't have access to the script. I can't get Add-VpnConnection to work Reply to this post. Resolve Hello Michael, thank you for your comment.It is common to use a VPN when we are working remotely, and we need to access our company assets. If you work with Azure, you may notice that you can configure two types of VPN:. In this article, we will focus on how to connect our local network to our Azure Virtual Network.
To reach this goal, we will perform the following steps:. Select the Add button to create new resource group. Now we need to create a new virtual network. At this step, we need to create a Root Certificate and a Client Certificate. This will create the ROOT certificate and install it under current user certificate store. Once the certificate has been exported, then go to the Azure Portal, and open the Virtual Network Gateway blade.
Open a PowerShell console, and run the following script:. Then, you can download the VPN Client configuration in order to import it on your Windows 10 machine:. As you can see, the IP address is Two active routes has been created, so it means that when I try to reach the following network: Now, I can test my VPN connection.

Introduction It is common to use a VPN when we are working remotely, and we need to access our company assets. If you work with Azure, you may notice that you can configure two types of VPN: Site-To-Site VPN : Site-to-site is used when you want to connect two networks and keep the communication up all the time. The main difference is that if you log-off or restart the workstation, it loses connection, and you have to reconnect every time.
The following script has been released by the Microsoft Team:. Create a self-signed root certificate.Azure vpn certificate In the internet, I could not find any useful information about p2s client certificate except Azure VPN.
A client certificate that is generated from the root certificate. In the Certificate Export Wizard, click Next to continue. If you closed the PowerShell console after creating the self-signed root certificate, or are creating additional client certificates in a new PowerShell console session, use the steps in Example 2. When you try to connect to an Azure virtual network by using the VPN client, except for exporting the root certificate public key. On the far right of the taskbar, select the Network icon either or.
After few minutes Download VPN client option will be available to download the client software. When you use Azure certificate authentication type in the point-to-site configuration in the virtual network gateway. No VPN physical device is required and there are minimal, if any, changes required to be made to the on-prem network. You upload the root certificate including the public key information to the Azure portal, which is considered to be "trust" by Azure for connection over P2S to the virtual network.
It is for VPN clients. A Dynamic VPN gateway. If you want to P2S from a non-Windows machine and cannot utilize site-to-site S2S connectivity from a location to enable communication from old devices then the best option is a 3rd party VPN solution which can run in Azure as an appliance. When I investigate my certificates, I see that my FunnelFire and Root Agency certificates are both station that "This certificate has an invalid digital signature".
To add an additional trusted root certificate, see this section of the article. You upload the public key information of the root certificate to Azure.
It can occur in the Connect Client but it can also occur in a web browser or a test program for SSL connections. Right-click the client certificate that you want to export, click all tasks, and then click Export to open the Certificate Export Wizard. The VPN type must be route-based. You generate a client certificate from the self-signed root certificate and then export and install the client certificate. The key reasons for not offering cert-based IKE authentication is due to the additional compliance requirements and validations related to handling certificates.
Solution Extract the VPN client configuration package, and find the.In one of my previous articleI explain how we can create site-to-site VPN connection between local network and azure virtual network.
This VPN connection is initiated in your edge firewall or router level. But what if you connecting from remote location such as home? In this method it will use certificates to do the authentication between end point and azure virtual network.
In this exercise, I like to use separate resource group for virtual network and other components. Create Subnets. Before we create VN gateway, we need to create gateway subnet for it. Once it is in list, click on it. This is only supported with dynamic mode. It will only happen when gateway is deleted or read. If your organization using internal CA, you always can use it to generate relevant certificates for this exercise.
If you do not have internal CA, we still can use self-sign certs to do the job. As first step I am going to create root certificate. In Windows 10 machine I can run this to create root cert first. Next step of this configuration is to configure the point-to-site connection. In here we will define client ip address pool as well. It is for VPN clients. Then in new window click on Point-to-site configuration. After that, click on Configure Now link.
In this demo I will be using Linux and other mobile clients by default use IKEv2 to connect. For authentication type use Azure Certificates. In same window there is place to define root certificate.
Step 7.2. Create conditional access root certificates for VPN authentication with Azure AD
Under root certificate name type the cert name and under public certificate data, paste the root certificate data you can open cert in notepad to get data. Then click on Save to complete the process. Now we have finished with configuration. As next step, we need to test the connection. To do that log in to the same pc where we generate certificates. Log in to Azure portal from machine and go to VPN gateway config page.
In that page, click on Point-to-site configuration. After that, click on Download VPN client link. Then double click on the VPN client setup. In my case I am using 64bit vpn client. After that, we can see new connection under windows 10 VPN page.
Click on connect to VPN. Then it will open up this new window. Click on Connect in there. Then run ip config to verify ip allocation from VPN address pool. In VPN gateway page also, I can see one connection is made.
I generated an ssl certificate with openssl and when I install it to the trusted root certificate authentication store on my local computer the runs fine. However when I upload the cert via the management portal I get errors that the certificate isn't trusted which is correct and the correct error for when a certificate is not installed. How can I install a private SSL certificate into the trusted root certificate store on an azure web app?
Unfortunately, we cannot add a certificate to the trusted certificate authority on an Azure Web App. The security implications would be quite bad if that were possible. More detail info please refer to another SO thread. But We can use Azure Cloud Service that allowed us to do that. More info please refer to the document. If we want to install certificates to Personal certificate storewe could upload a. Then the certificates will be installed to the Personal certificate store.
The easiest way to get an SSL certificate that meets all the requirements is to buy one in the Azure portal directly. This article shows you how to do it manually and then bind it to your custom domain in App Service. Learn more.
