The firewall has blocked Internet access to the all routers multicast address (224.0.0.2) (ICMP Router Solicit) from your computer.
Multicast Address
The IP address you specified:
224.0.0.2
is what\'s called a "multicast address". The standards for assigning multicast addresses are still being developed. The idea is that one IP address, in the range 224.x.x.x - 239.x.x.x, can mean a set of different computers. The computers in the multicast could be on the same or different networks or subnets.
Standards for assigning multicast addresses are still being developed.
This kind of IP address can only be used as a destination address. Even as a destination address, unless you are on a network that is actively involved in the development of the system for assigning IP addresses, it was probably spoofed (faked). If a multicast address shows up in an alert as a source address, it was almost certainly spoofed. A group of computers can\'t send a data packet across a network.
wie gesagt die meldung kommt nur beim verbindungsaufbau wenn ich die firewall auf stop stelle.das heisst ich unterbinde jeglichen datenverkehr nur die verbindung zum provider wird ausgeführt.benutze zonealarm.kann es sein das die ip local benutzt wird oder ist das ein internet block?habe ein programm das mir alle ip anzeigt die online sind aber die multicast nicht.kannst du mir sagen was für ne funktion die hat?
danke
