ICMP. The screen appears as shown.
If an outside user attempts to probe an unsupported port on your P-660HWP-Dx, an ICMP
response packet is automatically returned. This allows the outside user to know the P-
660HWP-Dx exists. Your P-660HWP-Dx supports anti-probing, which prevents the ICMP
response packet from being sent. This keeps outsiders from discovering your P-660HWP-Dx
when unsupported ports are probed.
