    Hi all.

    I dont know why but if i scan my Router for open Ports it shows me always that my Ports 23,443 are open?? I didnt have any Service or Port Forwarding (open Ports) config i didnt also have a Remote Management ON.

    I didnt use Telnet.

    So why are these Ports are open if i make an Online Scan with different Online Scan Services??

    Question about Question with this NEw Firmware...........

    Online Scan with PC Flank.

    Try using "shields up" at http://www.grc.com .

    Blue means the port is "visible, but closed; red means the port is "visible" and open.

    By design, port 443 is open to allow for communication with quickvpn (illustrated in red) whereas telnet is illustrated in blue.

    Although port 443 is open to accept communications and is visible, an attacker would have to be sitting and waiting at the precise time you initiate a quickvpn connection to try and pick off your password. There has been numerous thoughts of how insecure quickvpn is but in the end, they are "hypothesis" because most of the supposed attacks are based on the attacker knowing (without a shadow of a doubt) "when" and where" you'll be logging in.

    Alles ist gut...

    You can probably tell by my spelling that I haven't written it much either (my wife is German).
