we have a single machine deployment and want to easily use the new web mapping applications (and maybe extent them later). Own services must be secured due to copyright issues by the own Portal, so AGOL is not an option.
This all runs on a virtual machine with WinServer and IIS.
I have installed
ArcGIS Server 10.5.1 federated by Portal
ArcGIS Portal 10.5.1
WebAdaptor (arcgis) configured for both above
All SSL certificates are running and Reverse Proxy Server is working
Now, Webapplication from the Portal with content from ArcGIS online is running on a different webserver, but I cannot add services from ArcGISServer to Portal and thus to any webapplication. Likewise, I want to use specific services without Portal in small web applications. Thus, I need somehow to get the rest connection but this is currently hidden in the company network.
What to do? What might be wrong?
EDIT: Do I need two Webadaptors and two reverse Proxy forwarding, as internally in the company everything is working?
