Trying to add hosts that are behind a NAT IP translation and on an untrusted domain to snapcenter. after much digging it looks like the process uses WMI calls and the underlying DCOM to enumerate the host and then cannot access the host when it returns info with a local rather than Nat'd IP. error returned in logs is
The object Exporter specified was not found (Exception from HRESULT: 0x80070776)
Connection failed. Error: failed to find host (xx.xx.xx.xx) ...
End Checking for host connection

Note on the target host I can see the server has called the plug-ins and retrieved the information required so we know comms paths are in place, but something in the process is stopping the add host completing.
I get the same results from the GUI and PS Add-SMHost commandlet.
Can you please confirm if Snapcenter has been tested and can support the use of plug-in hosts behind a NAT firewall?
