Hi

You can use the Access Restrictions under the networking blade of your app service. You can add the IP addresses for Front Door in there and you do not need to use any Vnets etc.

the list of AFD IP Addresses are in the following ranges:-

IPv4 - 147.243.0.0/16

IPv6 - 2a01:111:2050::/44

@AnshulJain-6454 To elaborate on above said Access restrictions enables you to define a priority ordered allow/deny list that controls network access to your app and the list can include IP addresses or Azure Virtual Network subnets. When there are one or more entries, there is then an implicit "deny all" that exists at the end of the list.

You may refer to this doc might be helpful: https://docs.microsoft.com/en-us/azure/app-service/app-service-ip-restrictions#managing-access-restriction-rules
