We use CRM online, but this needs access to a line of business application that is on premise.
We need to lock everyone out except CRM online to access this application web services.
How do set this up?
I know CRM online has the following IP range:
https://support.microsoft.com/en-us/kb/2728473
But that is for accessing CRM online, we want the IP range that CRM online will use to contact web services.
Any help?
