That breaks if there's any NAT between the client and the gateway. Consider this technique:

> In a real Vision client, you can obtain the local MAC addresses with the following script: from java.net import NetworkInterface # Get list of local mac address as strings def myMacIds(): macs = [ni.hardwareAddress for ni in NetworkInterface.getNetworkInterfaces() if ni.hardwareAddress] return [":".join(["%02x" % (b & 0xff) for b in mac]) for mac in macs] Also, again in a real Vision client, you can obtain the outbound network interface and the corresponding local IP address the clien…

Note the use of a fake UDP connection (no actual packets sent) to coerce the OS to expose the source interface and IP selected for the route to the Ignition Gateway.
