Neue Fritz Box WLAN 3370 verursacht Default Drops im Firewall Log

Benni345
Hey,

und zwar habe ich heute meine alte Fritz Box (WLAN 3170) zu einer neuen WLAN 3370 ausgetauscht...

Der Grund war, dass IPTV von der älteren Fritzbox nicht unterstützt wurde.

Die neue FritzBox hatte die gleiche IP wie die alte und nach standardmäßiger Einrichtung sieht auch alles wieder gut aus.

Doch mir sind im Firewall Logfile "komische" Default Drops aufgefallen:

    Hey,

    hab durch suchen in google herausgefunden, dass diese IP's für Multicastpakete stehen, die von der Fritz Box ausgesendet werden.

    Hierzu auch ein Link:

    Internet Group Management Protocol

    Und das noch: 

    I see, in the Firewall events, many blockings of the IP address 224.0.0.1.

    Can someone tell me what this is?

    I run one laptop, (XP Home, SP3, CIS latest beta), on a wireless connection to a Linksys home gateway.

    Don't worry. It's not from the any web site. Also it's not hacking attempt.

    It's from your ISP's router.

    We say Multicast. The router which from your ISP sends multicast packets to evrybody have same IP range.

    Why do that?

    It means 'is there any hosts(PC) which belong to multicast group?'.

    Because the router should manage it's 'Routing Table'.

    It sends same packets every 1min(it depands on configuration).

    If you don't want to see that message Turn off Stealth port.



    Man lernt ja nie aus ^^
