I am wondering if there is a way to completely disconnect the cellular connection and use strictly ethernet for the gateway unless the ethernet is down. I know the MultiWAN feature allows for the cellular backup, but upon testing I am seeing it is still using data (I assume this is the data pings it is using to check if cellular is available). Is this data usage avoidable at all or is data usage a must have when having this set up?
Another question I have would be how much data could I expect the gateway to use when on an ethernet connection but having cellular on as backup? I am seeing right now somewhere around 0.40MB per day. Is this expected?
