Ingesting Data from an Isolated Network

[Moose]

I have a client that has Splunk deployed on their business network, and they would like to ingest data from an isolated network. The isolated network can send data outbound, but not receive inbound connections/communications. My recommendation was to collect the data on the isolated network and push it out to Splunk via one way file transfer. Then have Splunk monitor the file(s).  Has anyone else run into this scenario? If so, how did you architect a solution and was it successful? My assumption is that Universal Forwarders will not work in this situation because they require two way communication via TCP.

Thank you

So the "isolated" network is not truly isolated.  No problem.  Install one or more UFs on the network to send the desired data to Splunk.    All required UF communication is initiated by the UF so there's no need for "two-way" (all TCP is 2-way) communication.
