QUESTION
I am able to establish a connection on both the IT and the OT side of the bridge but I do not get any data through. What could be the reason?
ANSWER
This could be because the UDP traffic is blocked but the TCP traffic is getting through (usually because of some kind of firewall setting). This will be indicated by a flashing OT LED.
