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.

Description

Port and protocol

Input/Output

FLOW REST API & communication between FLOW Insights and FLOW Block

8088/TCP

Input

Communication between FLOW Insights and FLOW Node

5556/TCP

Input

FLOW video server

8090/TCP

Input

FLOW UDP server

55570/UDP (configurable)

Input

FLOW webhook outputs

?/TCP (port is defined by receiving part)

Output

Note that is it possible to connect to multiple FLOW devices with single IP using port forwarding. It is necessary to specify two ports when accessing the devices this way, the FLOW Block - 8088 (for transfer of traffic data) and FLOW Node - 5556 (for image data transfer). When logging into the device in FLOW Insights, type your IP address and ports in the following format [IP]:[PORT BLOCK]:[PORT NODE] as shown in the example below.

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.

Description

General-purpose ports:

The RTSP for receiving video feed from the camera is critical for running FLOW. The rest depends on the specific cases.

Port taxonomy:

output = FLOW device creates a connection to the target port

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