You may want to change your [GPS location sharing settings](gps#location_share) if you are enabling this. It will broadcast your location over the internet.
If your device is connected to WiFi you can enable it to forward messages along to an MQTT server. This allows users on the local mesh to communicate with users on the internet.
If a meshtastic node is able to reach the internet it will normally attempt to gateway any channels that are marked as `is_uplink_enabled` or `is_downlink_enabled`. But if this flag is set, all MQTT features will be disabled and no servers will be contacted.
This is a channel specific setting. If your channel has this set to `true` and you are connected to WiFi, the device will forward along messages to whatever MQTT server is specified in `mqtt_server`.
### is_downlink_enabled
This is a channel specific setting. If your channel has this set to `true` and you are connected to WiFi, the device will forward along messages from the MQTT server to the mesh from this device.
