I am researching how to convert a Intranet (internal) web map application to a Internet (external) web map. The data is private. Theoretically, I want the user to be able to access it outside of the internal network. I may be able to copy the Web viewer and paste it to a HTTP. If the user has to access if via a 'Sign In,' then this approach will work. I cannot use ArcGIS Online. I do not have ArcGIS for Portal. I have ArcGIS for Server 10.1.
Looking for options via ArcGIS for Server, Sign In, or another approach?
