Re: Closed vs. Filtered
The frequently used association of STEALTH with INVISIBLE is snake oil.
In case you wouldn't be there the nearest router located at your provider would respond with
"ICMP-Host unreachable"
No answer means that you are there and the requests have been dropped by a packet filter(FW)
REJECT means an active refuse of a connection attempt with a special ICMP message.
DENY means to throw away the connection attempts. The inquiring computer gets a timeout in this case. |
