How to Use Azure Front Door for a website publihed to internet via our hub Vnet?

Question

We use hub and spoke architecture where in we publish our web apps to internet via our hub that's has the required IPS/IDS tolls in place. So we want traffic to be routed via our the hub. The web site is hosted on vm's configured with load balancer in private mode . And load balancer endpoint is published to the inter via hub. This means that we use our own ip's on the internet. . My question is How Can I set up Azure Front Door service to point to an internet website as backend? I understand there will be some caching happening at Edge location but rest of the traffic must come via the hub.

Hello @a-ksekhon , Thank you for reaching out. I think I did not understand the question correctly can you please share your network diagram?
Azure Front Door requires that the backends are defined either via a public IP or a publicly resolvable DNS hostname. Members of backend pools can be across zones, regions, or even outside of Azure as long as they have public connectivity. So wherever your public IP is hosted the request will be forwarded to that end point.

Additionally if you want to add a different resource in Azure select Custom host as your backend host type. Please let me know if you have any additional concerns.
