14.3 Services Screen

If an outside user attempts to probe an unsupported port on your LTE3301, an ICMP response
packet is automatically returned. This allows the outside user to know the LTE3301 exists. Use this
screen to prevent the ICMP response packet from being sent. This keeps outsiders from discovering
your LTE3301 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.
Click Security > Firewall > Services. The screen appears as shown next.
