Respond to Ping

The Prestige will not respond to any incoming Ping requests when Disable is selected.

on

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.

 

 

Do not respond

Select this option to prevent hackers from finding the Prestige by probing for unused

to requests for

ports. If you select this option, the Prestige will not respond to port request(s) for

unauthorized

unused ports, thus leaving the unused ports and the Prestige unseen. By default this

services

option is not selected and the Prestige will reply with an ICMP Port Unreachable

 

packet for a port probe on its unused UDP ports, and a TCP Reset packet for a port

 

probe on its unused TCP ports.

 

Note that the probing packets must first traverse the Prestige's firewall mechanism

 

before reaching this anti-probing mechanism. Therefore if the firewall mechanism

 

blocks a probing packet, the Prestige reacts based on the firewall policy, which by

 

default, is to send a TCP reset packet for a blocked TCP packet. You can use the

 

command "sys firewall tcprst rst [onoff]" to change this policy. When the firewall

 

mechanism blocks a UDP packet, it drops the packet without sending a response

 

packet.
