If there is a VOLTTRON central deployment on ZMQ, would I need to have network ports on a firewall opened up if the actual VOLTTRON central instance is behind a firewall?
Basically I am looking at deploying an edge device in a building to collect some BACnet data (temporary research deployment) and hoping to aim this edge device instance to our central VOLTTRON instance that runs a SQL historian that is behind a firewall.
Does ZMQ run on port 5555? And I would I need to have our firewall opened up or port forwarding on this port to handle the bi-directional ZMQ bus?
