13.8 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.

DESCRIPTION
Internet Control Message Protocol is a message control and error-reporting
protocol between a host server and a gateway to the Internet. ICMP uses Internet
Protocol (IP) datagrams, but the messages are processed by the TCP/IP software
and directly apparent to the application user.
The Prestige will not respond to any incoming Ping requests when Disable is
selected. Select LAN to reply to incoming LAN Ping requests. Select WAN to reply
to incoming WAN Ping requests. Otherwise select LAN & WAN to reply to both
incoming LAN and WAN Ping requests.
