To change your Device’s security settings, click Maintenance > Remote MGMT > ICMP. The screen 

appears as shown.

If an outside user attempts to probe an unsupported port on your Device, an ICMP response packet 

is automatically returned. This allows the outside user to know the Device exists. Your Device 

supports anti-probing, which prevents the ICMP response packet from being sent. This keeps 

outsiders from discovering your Device when unsupported ports are probed.
