Solicited TCP Packets: PASSED — No TCP packets were received from your system as a direct result of our attempts to elicit some response from any of the ports listed below — they are all either fully stealthed or blocked by your ISP. However . . .



Unsolicited Packets: PASSED — No Internet packets of any sort were received from your system as a side-effect of our attempts to elicit some response from any of the ports listed above. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system remained wisely silent. (Except for the fact that not all of its ports are completely stealthed as shown below.)



Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since "Ping" is among the oldest and most common methods used to locate systems prior to further exploitation.

Dear Mr. Devid,

Thank you very much for your enquiry.

The reply to ICMP requests to the public IP address of the FRITZ!Box cannot
be deactivated and does not pose a security risk!

The reply to ICMP requests is technically useful as ICMP packets are used
by certain TCP/IP services (e.g. FTP connections or online games) in order
to verify the connection to the client. This can lead to interferences of
such TCP services when no or no useful reply is returned. Therefore, it is
not intended to completely disable the reply of ICMP packets.

Incoming ICMP requsts do not pose a security threat to computers connected
to the FRITZ!Box as they are only directed to the public IP address of the
FRITZ!Box and cannot be answered by the connected computers but only by the
FRITZ!Box itself.

A mechanism in the FRITZ!Box protects against a threat of a so-called
"denial of service (DoS) attack" that only allows a defined number of ICMP
packets (e.g. "pings") to be replied within a certain time frame and
discards the others. Thus it is not possible that a great number of ICMP
packets can cause the  FRITZ!Box to become inoperative.

Best regards,

Hier ben ik het niet mee eens volgens mij is er iets anders aan de hand ik benaltijd met een fritzbox 7170 onzichtbaargeweest en ze zijn van zelfde leverancier
Wat kan ik nog meer doen zit ik in een botnet ofzo of heb ik een virus zoja hoe kom je erachter?
