Access azure app service using f5 LTM

Hi thank you for your response .

I have attached the diagram for your reference. It may be confusing. Our requirement is to access Azure App Service using F5. F5 is not directly facing the internet; it works as a backend pool of the Azure Load Balancer. The pool I created in F5 using "abc.com_pool_app1," and the node I added is "abc.com" with FQDN, resolving to the IP of AZ-LB.
In f5 and az lb 443 as frontend and 6558 as backend port we are using .
