If an outside user attempts to probe an unsupported port on your LTE Device, an ICMP response packet
is automatically returned. This allows the outside user to know the LTE Device exists. Use this screen to
prevent the ICMP response packet from being sent. This keeps outsiders from discovering your LTE
Device when unsupported ports are probed.
You can also use this screen to enable service blocking, enter/delete/modify the services you want to
block and the date/time you want to block them.
