Hello,
We are in the process of documenting cybersecurity for the device below. I’ve previously reached out about password complexity. We are now trying to confirm all the TCP and UDP ports for the devices. Per the manual, our initial answer is TCP 502 ModBus for the gateway and TCP 80 HTTP for the web server. However, some scans of the device have revealed others that we need to confirm with you since they aren’t in the manual. Can you verify they are active and what service/purpose they provide?
