16.9 Security Screen

To change your Prestige's security settings, click the Remote MGMT link under
Management and the Security tab. The screen appears as shown.
If an outside user attempts to probe an unsupported port on your Prestige, an ICMP response
packet is automatically returned. This allows the outside user to know the Prestige exists. Your
Prestige supports anti-probing, which prevents the ICMP response packet from being sent.
This keeps outsiders from discovering your Prestige when unsupported ports are probed.
