The Dynamics 365 Portal is public when provisioned and accessible by anyone from any computer. Now we can restrict access to the portal from a list of IP addresses using ‘Set up IP address restriction’ page from your Portal Administration screen.

How it works:

• To allow access to a portal from an IP address or a set of IP addresses, you can add the ‘Public’ IP addresses to the list. This allows the portal to be accessed only from the list of added IP addresses. If no IP address added, the portal will be accessible from all IP addresses.
• When a request to the portal is generated from any user, their IP address is evaluated against the allow list. If the IP address is not on the list, the portal displays a web page with an HTTP 403 status code.
• Only Public IP addresses are allowed and  Private IP address can’t be accessed by the portal.
• If you try to access the portal from any other IP addresses, access will be denied and a web page with an HTTP 403 status code is displayed.

Steps to Add/Remove IP Addresses:

• Login to your Dynamics 365 Administration Center
  • You must be having a Office 365 Global Administrator/ Dynamics 365 Service Administrator
• Select your Instance and go to ‘Applications’ tab.
• Select the ‘Portal Add-on’ from the ‘Applications’ list and click ‘Manage’

• From the Portal Administration screen, select ‘Set up IP address restriction’

• Click on + to add new IP address

• To remove the IP address, use X from the grid.
