I'm having lots of mixed results with the UDP functions. Host to target and back is fine, UDP open/write/read. When I try to read from target 1 at IP1 and send to target 2 at IP2, both targets on the same input/output ports, nothing goes out to target 2. Wireshark shows data going to that IP but the led on the router isn't even blinking. I'm sending 120 byte packets at 30ms frame rate. Most times labview locks up to the point I have to reboot the pc.
We need more information than what you provided to actually try to help you. Can you post the code or a subset of it that shows the problem. I think you will also need to provide examples of your IP address assignments and the ports that you are using.
