63 == Monitor Public IP ==
64
65 The monitor_gateway.sh has been updated to upload the public ip of the device as well.

67 User can find the public ip in field7, the chart is not able to show the complete public ip, user can check that in the export.

83 * Remote.it access will give full control of your device to remote support.
84 * The Remote.it allow Dragino Support to remote access to the device, If user want to access himself, it need to sign up for an remote.it account.
