I am developing a portal page for Anonymous Users.
Since it is under development, I would like to restrict external access.It would be nice to have a function which enable it.
We have release functionality to restrict Portal access from certain IP Addresses, this can be used to do this scenario. Details can be found here https://docs.microsoft.com/en-us/dynamics365/customer-engagement/portals/ip-address-restrict
