Best SCCM CMG Cloud Management Gateway Implementation Guide

In this post, let’s check the SCCM CMG Cloud Management Gateway Implementation Guide. SCCM Cloud Management Gateway (CMG) architecture and its co-management environment are discussed in Part 1.

In this post, let us consider how to configure SCCM CMG with fewer certificates (New SCCM CMG Setup Guide).

The option to deploy a Cloud Management Gateway (CMG) as a cloud service (classic) is deprecated. All CMG deployments should use a virtual scale set.

The Cloud Management Gateway (CMG) provides a simple way to manage SCCM clients on the internet. The CMG is a PaaS (Platform As A Service) solution in Azure. So, we don’t need to maintain the servers in the Azure platform, unlike Azure IaaS (Infrastructure As A Service) solution.

We need to set up and configure Azure Cloud Services within SCCM before implementing Co-Management CMG. Co-Management CMG is not a prerequisite for all the SCCM Co-Management scenarios.

However, CMG is required for the scenario where you want to install an SCCM client from the internet. SCCM Cloud Management Gateway (CMG) & CDP are necessary for the above situation.

IntroductionBest SCCM CMG Cloud Management Gateway Implementation Guide

We all know that SCCM CMG is evolving. So, if you are planning SCCM CMG in your environment, Upgrade SCCM to the latest version to have more enhanced features of SCCM CMG.

You can refer to appropriate SCCM versions (SCCM 1810, 1902, and 1906) documentation. CMG has been many improvements (Cloud Management Gateway) with every new SCCM version.

NOTE! – Are you planning to replace SCCM IBCM servers with SCCM CMG? I recommend reading the following post, “SCCM IBCM Vs. CMG Differences a Real World Comparison.”

  1. Internet-connected SCCM client request for policy from Azure CMG cloud service
  2. Azure CMG cloud service forwards the client communication to the on-premises CMG connection point. CMG cloud service gets the policy from On-premise MP and SUP through the CMG connection point role.
  3. CMG connection point role acts as a proxy and builds a 2-way communication channel between on-premise SCCM (MP & SUP) and Azure CMG cloud service
  4. Finally, SCCM clients get policy and content from the Azure CMG cloud service.

Note:  CMG supports the management point and software update point roles only. More details about SCCM CMG-supported communications are available.

SCCM CMG Cloud Management Gateway Prerequisite

The following is the quick list of SCCM CMG setup prerequisites.

  • Unique CMG DNS name
  • Azure subscription to host CMG
  • Azure permission with Global Admin and subscription owner rights. 
    • Subscription admin permission to deploy CMG cloud service
    • Global /Service Admin permission to integrate SCCM site with Azure AD using Azure Resource Manager 
    • In this post, My ID already had the higher privilege with Global admin rights assigned, used for all configurations. Hence, I did not have to worry much about these prerequisites.
  • Internet access connectivity requirements 
  • Network ports requirements 
  • Windows 10 devices should have IPv4 enabled
  • server authentication certificate for the CMG
  • Service connection point in online mode. The service connection point is responsible for deploying the CMG in Azure.
  • On-premises Windows server to host the CMG connection point.

In this post, we host the CMG connection point role on a dedicated server and MP, and SUP with enhanced HTTPS enabled. If you already have HTTPS-enabled MP and SUP, then no need for a separate server.

Microsoft.ClassicCompute & Microsoft. Storage resource providers must be registered within the Azure subscription.

Before implementing the Co-Management CMG setup, I recommend reading CMG Prerequisite and Certificate requirements.

Seven steps for SCCM Cloud Management Gateway Configuration

SCCM CMG Cloud Management Gateway Implementation Guide.

CMG configuration steps New SCCM CMG Setup Guide SCCM CMG Cloud Management Gateway Implementation Guide

Infrastructure setup used for this post

Let’s check the infrastructure components used in the SCCM Cloud Management Gateway setup explained in this post.

  • AADconnect enabled hybrid Azure AD join.
  • SCCM 1902
  • Internal PKI CA for certificates.

In this post, we are not using a third-party certificate.

  • Dedicated site server with MP and SUP for CMG
  • Windows 10 1903 Enterprise
  • Let us cover each configuration step in detail

Verify unique SCCM CMG DNS

In this step, we need to identify the unique CMG service name that we will use later in SCCM. SCCM configures the CMG cloud service in the *.cloudapp.net domain. Hence, the CMG service in Azure must be unique and not used by anyone.

Note: we do not have to create the CMG service in the portal. SCCM will take care of deploying the CMG cloud service. We need to ensure the CMG service name is unique.

Below are the steps to Check the Unique service name

  • Sign in to the Azure portal. Search for Cloud service.
  • Select Cloud service and type the prefix in the DNS name field.
  • If the domain name is available, the interface reflects green color.
Cloud service Azure - New SCCM CMG Setup Guide SCCM CMG Cloud Management Gateway Implementation Guide
New SCCM CMG Setup Guide – Cloud Service -Best SCCM CMG Cloud Management Gateway Implementation Guide 3

If the Name is unavailable, the interface reflects red color. Try a new name if red.

SCCM Cloud management gateway can now serve Cloud distribution points as well. Below are the steps to Check a unique service name for the storage

  • Sign in to the Azure portal. Search for a Storage account. Select Create.
  • Type the name prefix in the “Storage account name” field.
  • Green tic state storage name is unique and available.
CMG Storage account - Best SCCM CMG Cloud Management Gateway Implementation Guide 5
New SCCM CMG Setup Guide – Storage Account -Best SCCM CMG Cloud Management Gateway Implementation Guide 5

Make a note of this unique Name. Later while configuring CMG wizard in SCCM, we will use this Name.

Step 1 completed 🙂 Let us proceed to the next step.

Certificate preparation – SCCM CMG Cloud Management Gateway Implementation Guide

To configure CMG, we need at least One certificate (Server authentication certificate). Based on the need or scenario, you may need more credentials; we need One certificate only (Server Authenticate in this post or scenario). Let us discuss server-side and client-side certificates.

Server Side certificate

Third-party vendors like DigiCert or Microsoft PKI can issue a Server authentication certificate. Certificate issued by both supported. In this post, we will use Microsoft Enterprise PKI.

The server authentication certificate is mandatory while configuring CMG for any scenario. In part 1 of this post, we discussed different CMG scenarios.

Note: Microsoft recommends using a trusted third-party certificate provider like DigiCert. Windows 10 trusts these third-party certificates without any Root certificate dependency. We will discuss more in later sections.

Let us discuss the steps to get the server authentication certificate.

SCCM CMG Setup Guide Client-Side certificate

Why is a certificate required on the Windows 10 or Windows 11 client for CMG?

SCCM client must authenticate to confirm its identity before communication with CMG cloud. There are three options for authentication. In this post, we will use 3rd option.

  1. PKI client authentication certificate or
  2. User identity token (Azure AD user discovery) or
  3. Azure AD computer identity (Using Default Azure client Auth certificate)

By default, Hybrid or Azure only joined computers will receive below two certificates from Azure. These certificates can serve as an authentication token for CMG service. In this post, we are using these two certificates.

Azure certificate Intune SCCM CMG Cloud Management Gateway Implementation Guide
New SCCM CMG Setup Guide – SCCM CMG Cloud Management Gateway Implementation Guide 19

Note 1: if we use Microsoft internal PKI, the Root CA of your internal PKI CA is required on the Windows 10 client.

Note 2: if you are using third-party certificates like Entrust, user trust that, DigiCert, etc., then Root CA is not required. You do not need any roo even for Azure AD connected machines CA even for Azure AD connected machines. Unlike Microsoft enterprise PKI, Windows 10 trusts third-party certificates without any need for root CA. This reduces the complexity and root CA dependency on the client-side. Microsoft recommends third-party certifications because of this rationale.

Azure Service integration with SCCM | SCCM CMG Setup Guide

In this step, we will integrate SCCM with Azure cloud services. This integration was performed using the SCCM Azure Services Wizard. For more configuration details on Azure Services wizard, refer here.

This wizard can configure two things.

  • Azure AD web app registration: SCCM clients use Azure web app URLs to authenticate with Azure.
  • Azure AD user discovery (optional): We will not configure. We have already discussed that the user identity token is not used for authentication in this post.
  • Navigate to Administration > Overview > Cloud Services > Azure Services.
  • Right-click Azure Services and click Configure Azure Services.
Azure Services SCCM - Best SCCM CMG Cloud Management Gateway Implementation Guide

New SCCM CMG Setup Guide – Cloud Services – Best SCCM CMG Cloud Management Gateway Implementation Guide 21

In the below wizard, we have to configure Webapps. Check with your azure administrator before deciding whether you can use existing web apps or new webapps for CMG.

You have two options. In this guide, we use the second option.

(1) Pre-create the Azure webapps manually and import them in the below SCCM wizard. For more details about the configuration, refer.
(2) SCCM creates the Web app automatically in Azure.

You are signed in with a Subscription Admin and select the default web URL.

Azure webapps - New SCCM CMG Setup Guide SCCM CMG Cloud Management Gateway Implementation Guide
New SCCM CMG Setup Guide – SCCM CMG Cloud Management Gateway Implementation Guide 23

In this post, we are not enabling user discovery. Let us discuss why we are not enabling. There are two reasons.

(1) Authentication: This post uses the SCCM client’s computer identity (certificate) for CMG authentication. Therefore, we do not need a user token for authentication identity.

2) Deployment: In my scenario, SCCM deployments will be device-based instead of user-based. However, you can consider enabling user discovery if that is not the case.

CMG deployment configuration in SCCM

We have done a lot of prep work. Finally, we reached the step to deploy the CMG service in Azure using the SCCM console. While configuring CMG cloud service, please ensure CMG is configured at the top-tier site of the SCCM hierarchy.

  • On the ConfigMgr Console, go to Administration > Cloud Services > Cloud Management Gateway.
  • Click Create Cloud Management Gateway on the ribbon menu.

Browse and select the Server authentication certificate that we exported in step two.

The CMG service name will auto-populate from the certificate we provided while importing the certificate in Step 2. The CMG Service name will populate with the XXXX.cloudapp.net domain name.

Note: CNAME is required if you are using the custom domain name. You have to create a CNAME record in public DNS pointing to

Select the Region – The Azure region where the cloud service to host. For the China region, I would recommend checking with Microsoft.

  • Select the option new resource group.
  • Select the group from the drop-down menu.

Choose the number of VM Instances. The maximum VM instance value you can provide is 16. Each standard VM A2 hosted in Azure can support approx 6000 clients. In addition, 2000 simultaneous connections.

In production, consider multiple VM for redundancy or availability. You can add “instance” to the existing CMG, which can be done simply by adding another VM. There is no need to have an additional CMG cloud service for HA because the Azure CMG cloud service is already on HA.

Un-check “Verify Client Certificate Revocation.” We are not using a PKI client authentication certificate in our scenario, so this setting is not relevant to us. Clear this if you have not published the CRL on the internet. Recommended checking with your security or PKI team.

Since we are using Internal CA Cert for CMG, upload respective Root and Intermediate certificates.

Enable the CMG to serve as a cloud distribution point as well.

  • Click Next to proceed and configure the CMG cloud service.

Install CMG connection point role | SCCM CMG Setup Guide

In previous step four, we deployed the CMG cloud service. This step will install the CMG connection point SCCM role on-premise and connect with the CMG cloud service.

The CMG connection point role can be installed on the remote Site System server with or without MP/SUP rode; I have a dedicated CMG role with MP and SUP enabled for H in this guide.

Ensure internet proxy allows CMG connection point communication with CMG cloud service.

Note 1: multiple CMG connection point role installed servers can communicate with a single CMG cloud service.
Note 2: it is also possible to create multiple CMG cloud services and connect with various CMG connection point role servers.

Having multiple CMG connection point roles is load balancing of client traffic from the CMG cloud service to the on-premise MP/SUP. Refer here for more details on planning the CMG in SCCM hierarchy design.

  • Let us go through the steps to configure the CMG role. In the SCCM console, go to Administration > Site Configuration > Servers and Site System Roles.
  • Right-click the site server to Add Site System Roles.
  • IN THIS POST SCENARIO, the CMG connection role is installed on a dedicated remote server.
  • Provide the remote site server name.

SCCM CMG Site system & MP settings

In this step, let us enable component roles (MP/SUP) and the site system to respond to CMG requests.

With this configuration, SCCM clients from the internet communicate with on-premise MP and SUP through CMG cloud service.

I dedicated a remote SCCM server with MP, and the SUP role enabled CMG communication in this post only.

Note: CMG supports only two roles: SUP and MP

Enable the MP for CMG – SCCM CMG Cloud Management Gateway Implementation Guide

Navigate to Administration > Site Configuration > Servers and Site System Roles.

Select the Site Server holding the MP role (planned for dedicated CMG communications).

Check the “Allow Configuration Manager cloud management gateway traffic on the Management Point Properties.”

Change the connection to “Allow Internet-only connections.” Because in my setup, there is a dedicated MP server for CMG. Also, we want to ensure only internet-connected SCCM client requests communicate to the local MP.

Client Agent Setting for SCCM CMG

Creating a custom SCCM client agent setting is recommended to enable CMG instead of Default client settings. Custom client agent settings provide better control. You can use SCCM collection and custom SCCM client agent setting to restrict the number of clients to use the CMG.

  • Go to Administration / Client Settings.
  • Click Create Custom Client Device Settings on the top ribbon and select cloud services.
  • In the custom client agent settings, enable the option “enable clients to use a cloud management gateway.”
  • Enable “Allow access to the cloud distribution point.”

  2. I am unclear about something in the Client Side Certificate section.
    you mention:
    By default, Hybrid or Azure only joined computer will receive below two certificate from Azure. These certificates can serve as authentication token for CMG service. In this post, we are using these two certificates.

    are you exporting the certs from a Azure joined machine and then uploading from the CMG wizard?

If your authentication cert has been provided by the authority, Open your certificate and look at the Certificate Path tab, right click on the top line which should be your root CA and view cert, then Details, Copy to file (Leave as default .cer format), then select this file when configuring the client part.
    Double check that your clients already have this cert in the Trusted route store.
    Hope that’s what you were looking for.

  8. In the blog mentioned that created a separate server for SUP for CMG communication. So the system which is in intranet will receive the on-prem SUP server name, if it switches over to internet how much time will it take to switch to new SUP ( configured only for CMG Communication). How Software update point switching will work here. will it create any more network bandwidth?

    • Yes or Azure AD join might help in this scenario. If you don’t have hybrid azure ad join, then you might need to use public or client cert if cmg authentication from client side .

  9. Hi Anoop,
    May I suggest to add a verification step on the certificate template step : check that the server’s security group had also “Request certificates” permission on the CA.
    I’ve carefully followed the procedure you described and I’ve lost hours to figure out why it was not working. This permission simply was missing.

  10. Hello. At what intervals do the laptops check into CMG and determine if connection type is internet or intranet?

  11. I have two ConfigMgr environement (INT and PROD) and I would like to setup CMG on the SAME Azure Tenant.

    Is that possible ?
    which ressource can be shared ?
    for example : can the application be shared, if no, what are the settings for the URI and the URL

  12. Does this all work in a CSP Subscription, or is any other form of Subscription apart from CSP required for CMG to be deployed? I’ve checked the docs, however these are unclear as they say classic service is not required and two sentences later they say it’s still used. So what’s actually applicable?

  13. Hi, I have setup the CMG without a full Co-Management. But now I see that all workloads have been taken over by SCCM. Since I do not have a full Co-Managment configure, is there any way to move workloads back to Intune. I only need the SCCM agent for inventory.

  14. Hi, great post thanks in advance!
    I followed the instructions and set up the CMG config with ehttp and Azure AD hybrid join as client authentication. i only have one management point and therefore allow intranet and internet connections. with the CMG role everything looks fine. (no Errors in the SMS_Cloud_ProxyConnector.log and CMG-ourcmgname-ProxyService_In_0-CMGService.log)

    However, the clients do not receive a CMG URL. (Cloud Services Agent settings are configured correctly)
    The ClientLocation.log does not show that the client is trying to reach an internet management point.
    what could be the reason for this?

  15. Great Document. Thank you for creating and sharing.
    One question: for the Server Certificate…is that generated on the Site Server or from the dedicated internet MP?

  16. Hello Anoop,
    Do we need Global admin permissions for onetime user or dedicated service account is required to configure CMG?

    Thanks and Regards,

  17. I have renewed the DigiCert certificate for SCCM CMG connection, imported it, then exported the .pfx to renew the CMG connection.
    There are no errors in the CloudMgr.log file, neither in SMS_CLOUD_PROXY_CONNECTOR.log one.
    The connection analyser found there is no connection between the CMG Channel and the main management point.
    I checked the newly delivered certificate using the Digicert tool for windows and found no private key is matching despite I could export it before from the certificates >personal store panel.
    I tried reinstalling the CMG connection point role,
    I tried reinstalled the management point role.
    Please help because clients can not connect to the CMG and poll policies.
