The cloud management gateway (CMG) provides a simple way to manage Configuration Manager client over internet.
In the previous posts we discussed about CMG prerequisites, server authentication certificate requirement for CMG, client authentication certificate reqiurment, SSL configuration for ConfigMgr site , ConfigMgr site integration with Azure Active Directory and CMG setup and client settings.
In this post, we will discuss about validating Cloud Management Gateway services and client communication.

Check CMG Status
Go to Administration > Cloud Services > Cloud Management Gateway and check the following
- CMG service status is Ready
- Select Connection Points tab at bottom of console and check if Connection Point status is Connected

While CMG service name is selected, click on Connection Analyzyer
Simulate the testing for Azure AD user
- Sign in with Azure AD user
- Click on Start to test the connections
Simulate the testing for SCCM client
- Select Client certificate
- Click on Browse and select Client Authenication Certificate
- Click on Start to test the connections

Check Client Policy
Verify that client has recevied the internet based management URL. Client should receive the policy while on intranet.
- On the client connected to Intranet, go to Configuration Manager client properties > network tab
- Verify that CMG service name is visible in Internet based management point option

Check if Clients Communicating from Internet
Perform below check for the machines which are connected to Internet. Client must have received Internet based management URL to be able to communicate with CMG.
- Go to SCCM console > Devices
- Add the Device online from Internet and Device online Management Point column
- If client is able to communicate through CMG, you can see the CMG management point URL

If you want to see the list of all machines which are online from Internet, you can quickly apply below critera.

Check CMG Role EndPoint Status
Go to Administration > Cloud Services > Cloud Management Gateway, select CMG Service Name and select Role Endpoint tab at bottom of screen.
You will see the communication status for Management Point and Software Update Point for CMG. You can see total number of requests in last 30 days. When configured a new CMG, the number of requests can confirm that client are able to communicate with SCCM via Cloud Management Gateway.
Monitor CMG Health from Monitoring > Cloud Management
You can also monitor Cloud Management Gateway health from ConfigMgr console Monitoring > Cloud Management pane. This dashboard shows the details such as client online from Cloud Management Gateway / Intranet Management Point, CMG traffic in last 30 days, Client online trends in last 30 days.
