Is there any step-by-step guide to setting up NiFi Site-to-Site with Remote Process Groups? Any details on what port range(s) needs to be available?
My setup: NiFi Producer provides data on output port "data-output" to be picked up by NiFi Consumer. While trying to get a simple setup running, I set "nifi.remote.input.secure" to false and "nifi.remote.input.socket.port" to 8082 in NiFi Producer (also added TCP ingress to the firewall). The Remote Process Group in NiFi Consumer has the "data-output" port turned on and is simply routing to LogAttribute for verification. Logs in NiFi Producer indicate that it's periodically establishing a socket connection with NiFi Consumer over ports in the 54000 - 55999 range, but no data actually comes across to NiFi Consumer. I added opened NiFi Consumer's firewall for ingress from 54000 - 55999. Eventually, we'll need to get it over SSL and lock down the firewall to a minimum required range, but I'm hoping to prove it out first. Any guidance would be greatly appreciated! Thanks, Brian
