Which network ports and firewall rules does KLANG need (KOS updates, Collect Logs)?

Finding and mixing KLANG devices only needs a few UDP ports. Installing a KOS update from KLANG:app over the network and Collect Logs need more, including a connection from the KLANG device back to the computer running KLANG:app. If only the discovery ports are open, updates seem to hang and the log file is incomplete.

All ports, directions and the firewall settings for Windows and macOS are listed in Network Ports & Firewall for IT. Share that page with your IT department.
