I am looking to deploy one Azure front door, we are in Hub Spoke architecture.

Front door - will be deployed in Hub

AD B2C - in different spoke, will be peered with Hub.

I want to configure in a way that no public access is allowed on both frontdoor and ADb2C, and all traffic should be router through firewall.

does front door support private end point ?

Appreciate your support.

    Hi AJMAL E ELLATH,

    Welcome to Microsoft's Q&A platform! Thank you for asking this inquiry.

    • Azure Front Door inherently uses anycast public IP addresses and does not support a private-only frontend IP. This design aligns with its purpose as a global, scalable service for internet-facing applications.

    Here’s a summary of how you might address the requirement for private-only access using other Azure services.

    1. Azure Application Gateway with Private Deployment: For a private-only access model, you can use Azure Application Gateway with a private deployment. Application Gateway supports private IP addresses and can be deployed within a Virtual Network (VNet). This allows you to have a private frontend while still benefiting from application layer load balancing. Refer: https://learn.microsoft.com/en-us/azure/application-gateway/application-gateway-private-deployment?tabs=portal
    2. Integration with Azure Firewall: You can use Azure Application Gateway in conjunction with Azure Firewall to control and secure traffic. Azure Firewall can enforce policies, restrict access, and monitor traffic between your Application Gateway and other resources within your VNet. Refer: https://learn.microsoft.com/en-us/azure/architecture/example-scenario/gateway/firewall-application-gateway

    Updated NOTE: Here are the limitations being the Private Endpoints supported for Azure Front door.
