Kernel32.dll ICMP Type 10, access to network?

i just recently bought a used laptop and downloaded a different firewall than i have used before.. Sygate Personal Firewall.
after i connected to the internet through my dial up connection i had this message pop up,.

"Win32 Kernel core component (Kernel32.dll) is trying to send an ICMP Type 10 (Router Solicitation) packet to [224.0.0.2].
Do you want to allow this program to access the network?"

ive said no to this, and then wasnt able to load any webpages. i didnt click yes, instead wanted to come online here using my regular computer and ask what does this message mean?

 

do i need to grant access to this to let any webpage work, or is this something bad that i need to say no to ??
