I have a distributed Splunk environment, meaning a SHC and IDX cluster connected via distributed search as outlined in the Splunk docs. I have a Splunk Cloud free trial, and was wanting to try out federated search to link the on-prem indexers to the cloud SH. However, I cannot get it to work. Has anyone accomplished this before? How the docs outline it to be is that you place the federated search provider pointing at a SH rather than a IDX, and is there ports that need to be opened on the Cloud side?
