On-Prem: Web app needs to consume APIs from D365 F&O, Which Ports Need to be Opened?

Posted on by Momochi 907
Greetings dears!
I have a .Net web application that was previously used to consume APIs from D365 FO deployed on the cloud.
It was simple, after registering an app on the Azure, we use the credentials provided by app registration (Client Id, Secret, Resource, Tenant), and it works fine.
Now, I'm looking into making this web app work on D365 which is deployed on-premise.
I know that the communication should go through AD FS server, where we register the application there and get the credentials (client ID secret, resource, tenant).
But since this is a private network, which ports needs to be opened between the .net Web App and the AD FS?
 
Any suggestions is appreciated!
Thanks in advance !

    Hi Momochi,
     
    Mainly it would be port 443

    I really appreciate your link, but it does not state my issue which is what ports needs to be opened between my .NET web app server and the AD FS server.
    Because the AD FS is located in a separate subnet, I need to open ports so they communicate.
     
    Thanks
