@Kevin.Herron, We have some modbus device that accept multiple TCP connection but only with different ports... 8 simultaneous connection 502 to 510.

We would like to use our **redundant gateway in warm mode** but It's not possible to ajust another modbus port on the backup node ? Any workaround ? **Feature request...** 2. We could have our gateway in warm mode, and disable the warm mode for those device. **Feature request** : disable warm mode on a per device basis ---

Hmmm. That would be straight-forward to add to my driver... ---

That was easy: [v1.1.2.231841656](https://www.automation-pros.com/ignition/Advanced%20Modbus%20Driver-1.1.2.231841656-v81.modl) (In my driver, port number is specified with the hostname. With this change, you can set a completely different host or port for the backup server.) My driver(s) treat warm as cold anyways, so it might have worked for you without this change.
