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

Necessary for the update of TrafficXRoads and TrafficEmbedded units via FLOW Insights

8089

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

FLOW mDNS

5353/UDP

Input

Note that it is possible to connect to multiple FLOW devices with a 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

Port and protocol

Input/Output

Web admin console

8000/TCP

Input

DataFromSky service VPN - 172.105.65.31

31228/UDP

Output

General-purpose ports:

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

Description

*** These ports are not required for installation, but are recommended for basic testing after installation is complete.

Port taxonomy:

output = FLOW device creates a connection to the target port

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