Where is nifi running? Does it use ssl ? So it's not the windows firewall and such? If you access browser from linux can you check in the browser settings that it uses bolt?
Or perhaps use cypher-shell (apt-get install cypher-shell) to access neo4j from linux to windows? Btw if you get this up and running, *please* write about it. Really good stuff.
