17.7 The ICMP Screen

To change your Device's security settings, click Advanced > 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.
