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.
