multicast connection trials from a home machine - is it regular?

["ruben" <rubenb () arnet com ar>]

> From the firewall log:
"blocked: Out ICMP;Router solicitation;localhost->224.0.0.2;Owner: Tcpip
Kernel Driver"
That is done (as the first outbound communication) every time the machine is
connected via dialup to the Internet. Is that a logical part of the process?
OS is Win98, firewall is Kerio, the rule CAN be modified, but the blocking
came as default in the firewall settings. What arises my doubts is that the
firewall blocks the attempt to connect to 224.0.0.2 but the http and mail
service go back and forth as usual. A short Google search shows some info
about multicast in NT machines, but nothing worthwile. I'm suspecting of
some backdoor sitting in this machine. Of course it can be a part of a
legitimate process. Can you enlighten me about this?
TIA, Ruben.-
