Restricting Access to CRM Portals

Hi,

CRM Portals is publically available all the time. There are times when you might not want the public to have access to a portal e.g. A test system, during development or when deploying updates. Following a deployment, you might want to test the updates but still not allow public access. What are the options for restricting access? Dynamics CRM now allows you to restrict access to Dynamics 365 (online) with trusted IP rules. Is there anything like this available for CRM Portals?

Regards

Chris
