Is there a way to restrict access to the OFS public URL to specific IP address ranges?

Summary:

Our organization is wondering if it is possible to restrict access to the OFS public URL by using a whitelist of allowed IP addresses to access the application.

We are aware that we can set up access from specific IP address ranges by using the login settings in the Login Policies page at the application level within OFS, but we would like to restrict access at the network level (i.e. redirect to an error page). I saw a question posted here about 9 months ago saying that this was not possible but I was wondering if anything has changed since then.
