They would/should be the same network
One thing i note - auto connect is disabled. Any reason? Are you commanding the node to connect as described in the built in help? I would recommend until you get up and running to leave "Auto Connect ` checked. FYI, in Node-RED, whenever you change a setting on a node, it is completely destroyed and re-created (i.e. connection is re-established with the new parameters you enter)
Did you check computer firewall?
Can you run wireshark to confirm packets are being sent?
Can you attach a debug (set to show complete msg) to the output of your FINS Read node. Also, add a catch node that is aimed at the FINS Read node & link that to a debug node (also set to show complete msg). Capture the full msg and post in a reply.
How to capture debug data for posting
There’s a great page in the docs (Working with messages : Node-RED) that will explain how to use the debug panel to find the right path/value for any data item.
Pay particular attention to the part about the buttons that appear under your mouse pointer when you over hover a debug message property in the sidebar.
