Hi @Juan Pablo Delgadillo Martinez , You can use Azure Active Directory Conditional Access policies to restrict access to Windows Virtual Desktop (WVD) only to users within your internal network. You can create a policy that blocks access for external users to a set of applications. To do this, you can create an inbound security rule that allows Remote Desktop Protocol (RDP) traffic to the subnet from anywhere. You can also add the public IP address of the machine under the Firewall section of the Networking tab to restrict public access to QnA Maker resources. Please let me know if you have any questions and I can help you further.
If this answer helped you please mark it as "Verified" so other users can reference it.
Thank you,
James
