Can the RV50 Airlink SMS device be used on a different subnet than the Ignition gateway machine is on? I see no setting for a default gateway or am I missing something.

Update from me:  
It was easier to configure the AirLink SMS device to the same subnet as Ignition gateway.

Although, I think there is a chance that AirLink would work for sending SMS from different subnet, when LAN \> Host Port Routing settings are assigned properly (check AirLink device manual (software configuration user guide) for details).
