If something does not work, it may be due to a firewall blocking a particular communication channel and / or poor network configuration. Here you can find all ports and communication protocols across all FLOW devices. For better clarity, the list is divided into three sections, i.e.:

FLOW framework specific ports:

These ports and protocols are critical to making the FLOW framework fully functional. Blocking some ports may cause some features/functions to stop working.

FLOW device service ports:

These ports are required for services related to the following products: T.Enterprise, T.XRoads, and T.Embedded systems. Get datasheets and manuals for the products here.

Port taxonomy:

output = FLOW device creates a connection to the target port

input = FLOW device listens for a connection on this particular port
