The following table describes the labels in this screen.
18.7 The ICMP Screen
To change your P-660HN-F1A’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 P-660HN-F1A,
an ICMP response packet is automatically returned. This allows the outside user to
know the P-660HN-F1A exists. Your P-660HN-F1A supports anti-probing, which
prevents the ICMP response packet from being sent. This keeps outsiders from
discovering your P-660HN-F1A when unsupported ports are probed.
Note: If you want your device to respond to pings and requests for unauthorized
services, you may also need to configure the firewall anti probing settings to
match.
