Set up cloud management gateway for Configuration Manager
Applies to: System Center Configuration Manager (Current Branch) The process for setting up cloud management gateway in Configuration Manager includes the following steps:
Step 1: Configure required certificates
Before requesting a certificate, confirm that the desired Azure domain name (for example, GraniteFalls.CloudApp.Net) is unique. To do this, log on to the Microsoft Azure portal, click New, select Cloud Service, and then Custom Create. In the URL field type the desired domain name (do not click the checkmark to create the service). The portal will reflect whether the domain name is available or already in use by another service.
Option 1 (preferred) - Use the server authentication certificate from a public and globally trusted certificate provider (like VeriSign)
When you use this method, clients automatically trust the certificate and you do not need to create a custom SSL certificate yourself.
- Create a canonical name record (CNAME) in your organization’s public domain name service (DNS) to create an alias for the cloud management gateway service to a friendly name that will be used in the public certificate. For example, Contoso names their cloud management gateway service GraniteFalls, which in Azure will be GraniteFalls.CloudApp.Net. In Contoso’s public DNS contoso.com namespace, the DNS administrator creates a new CNAME record for GraniteFalls.Contoso.com for the real host name, GraniteFalls.CloudApp.net.
- Next request a server authentication certificate from a public provider using the Common Name (CN) of the CNAME alias. For example, Contoso uses GraniteFalls.Contoso.com for the certificate CN.
- Create the cloud management gateway service in the Configuration Manager console using this certificate.
- On the Settings page of the Create Cloud Management Gateway Wizard: When you add the server certificate for this cloud service (from Certificate file), the wizard will extract the hostname from the certificate CN as the service name, and then append that to cloudapp.net (or usgovcloudapp.net for the Azure US Government cloud) as the Service FQDN to create the service in Azure. For example, when creating the cloud management gateway at Contoso, the hostname GraniteFalls is extracted from the certificate CN, so that the actual service in Azure is created as GraniteFalls.CloudApp.net.
Option 2 - Create a custom SSL certificate for cloud management gateway in the same way as for a cloud-based distribution point
You can create a custom SSL certificate for cloud management gateway in the same way you would do it for a cloud-based distribution point. Follow the instructions for Deploying the Service Certificate for Cloud-Based Distribution Points but do the following things differently:
- When requesting the custom web server certificate, provide an FQDN for the certificate's common name that ends in cloudapp.net for using cloud management gateway on Azure public cloud or usgovcloudapp.net for the Azure government cloud.
Step 2: Export the client certificate's root
The easiest way to export the root of the client certificates used on the network, is to open a client certificate on one of the domain-joined machines that has one and copy it.
Client certificates are required on any computer you want to manage with cloud management gateway and on the site system server hosting the cloud management gateway connector point. If you need to add a client certificate to any of these machines, see Deploying the Client Certificate for Windows Computers.
In the Run window, type mmc and press Return.
From the File menu, choose Add/Remove Snap-in....
In the Add or Remove Snap-ins dialog box, choose Certificates > Add > > Computer account > Next > Local computer > Finish.
Go to Certificates > Personal > Certificates.
Double-click the certificate for client authentication on the computer, choose the Certification Path tab, and double-click the root authority (at the top of the path).
On the Details tab, choose Copy to File....
Complete the Certificate Export Wizard using the default certificate format. Make note of the name and location of the root certificate you create. You need it to configure cloud management gateway in a later step.
If the client certificate was issued by a subordinate certificate authority you need to repeat this step for each certificate in the chain.
Step 3: Upload the management certificate to Azure
An Azure management certificate is required for Configuration Manager to access the Azure API and configure cloud management gateway. For more information and instructions for how to upload a management certificate, see the following articles in the Azure documentation:
Make sure to copy the subscription ID associated with the management certificate. You will need it for configuring cloud management gateway in the Configuration Manager console in the next step.
Step 4: Set up cloud management gateway
In version 1610, cloud management gateway is a pre-release feature. To enable it, see Use pre-release features from updates.
- In the Configuration Manager console, go to Administration > Cloud Services > Cloud Management Gateway.
Choose Create Cloud Management Gateway.
In Create Cloud Management Gateway Wizard, enter your Azure subscription ID (copied from the Azure management portal), and browse to the certificate file you used to upload as an Azure management certificate. Choose Next and then wait a few moments for the console to connect to Azure.
Fill out the additional details in the wizard:
Specify the name for the service which will run in Azure. Service name must be alphanumeric characters only and 3-24 characters in length.
Choose the Azure region you want the service to run in.
Specify the number of virtual machines you want to use for the service. The default is 1, but you can run up to 16 virtual machines for the service.
If you use an internet proxy for the cloud management gateway connection point, you need to increase the number of ports on the proxy by the number of virtual machines you use, starting at port 10124.
Specify the private key (.pfx file) that you exported from the custom SSL certificate.
Specify the root certificate (and any subordinate certificates) exported from the client certificate. The wizard accepts up to two root certificates and four subordinate certificates.
Specify the same service name FQDN that you used when you created the new certificate template. You must specify the one of the following suffixes for the FQDN service name based on the Azure cloud you are using:
Azure cloud FQDN prefix Public (commercial) cloud .cloudapp.net Government cloud .usgovcloudapp.net
Clear the box next to Verify Client Certificate Revocation (unless you're publicly publishing your CRL information).
Choose Next when you're done.
If you want to monitor cloud management gateway traffic with a 14-day threshold, choose the check box to turn on the threshold alert. Then, specify the threshold, and the percentage at which to raise the different alert levels. Choose Next when you're done.
Review the settings, and choose Next. Configuration Manager starts setting up the service. After you close the wizard, it will take between 5 to 15 minutes to provision the service completely in Azure. Check the Status column for the new cloud management gateway to determine when the service is ready.
Step 5: Configure primary site for client certification authentication
In the Configuration Manager console, go to Administration > Site Configuration > Sites.
Select the primary site for the clients you want to manage through cloud management gateway, and choose Properties.
On the Client Computer Communications tab of the primary site property sheet, check Use PKI client certificate (client authentication) when available.
Make sure to clear Clients check the certificate revocation list (CRL) for site systems. This option would only be required if you were publicly publishing your CRL.
Step 6: Add the cloud management gateway connector point
The cloud management gateway connector point is a new site system role for communicating with cloud management gateway. To add the cloud management gateway connector point, follow the instructions in Add site system roles for System Center Configuration Manager.
Step 7: Configure roles for cloud management gateway traffic
The final step in setting up cloud management gateway is to configure the site system roles to accept cloud management gateway traffic. Only the management point and software update point roles are supported for cloud management gateway. You configure each role separately.
In the Configuration Manager console, go to Administration > Site Configuration > Servers and Site System Roles.
Choose the site system server for the role you want to configure for cloud management gateway traffic.
Choose the role, and then choose Properties.
In the role Properties sheet, under Client Connections, check the box next to Allow Configuration Manager cloud management gateway traffic, and then choose OK. Repeat these steps for the remaining roles. Enabling the HTTPS option is also recommended as a security best practice, but is not required.
Step 8: Configure clients for cloud management gateway
After the cloud management gateway and site system roles are completely configured and running, clients will get the location of the cloud management gateway service automatically on the next location request. Clients must be on the corporate network to receive the location of the cloud management gateway service. The polling cycle for location requests is every 24 hours. If you don't want to wait for the normally scheduled location request, you can force the request by restarting the SMS Agent Host service (ccmexec.exe) on the computer.
With the location of the cloud management gateway service configured on the client, it can automatically determine whether it’s on the intranet or the Internet. If the client can contact the domain controller or the on-premises management point, it will use it for communicating with Configuration Manager. Otherwise, it will consider it’s on the Internet and use the location of the cloud management gateway service to communicate.
You can force the client to always use cloud management gateway regardless of whether it’s on the intranet or Internet. To do that, you set the following registry key on the client computer:\
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM\Security, ClientAlwaysOnInternet = 1
To verify that clients can contact Configuration Manager, you can run the following PowerShell command on the client computer:
gwmi -namespace root\ccm\locationservices -class SMS_ActiveMPCandidate
This command displays the management points the client can contact including the cloud management gateway service.
