Sorry, my bad, David. My port and traffic questions were not limited to cloud images. I have my own Neo4j server, which I normally can reach at home or on my phone, but at work this is not allowed. My network manager at work confirms the 7xxx ports are closed. I can surf normally to all regular web sites on port 80 or 443. However, it did not help to change the ports on my Neo4j server to port 80 or 473, so I am not sure what to tell him do. Does he only have to allow connections going out on 7474 and 7687, and then allow the responses back through the same ports? He is willing to help out.
