16.8 Configuring Security

To change your Prestige’s security settings, click REMOTE MGMT, then 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.
