When setting up on-premises Azure (Entra) MFA with the NPS extension, which ports are required by default for authentication?

Explanation

NPS uses UDP port 1812 for standard RADIUS authentication and UDP port 1813 for standard RADIUS accounting between the access device and the NPS server. The NPS extension communicates with Microsoft Entra ID over TCP 443 separately. Microsoft Learn: https://learn.microsoft.com/en-us/entra/identity/authentication/howto-mfa-nps-extension
