Is there something special I need to do to send data to a multicast IP and
have it go across a router? Router is a Win2000 Server connecting 2
networks via RRAS PPTP. The routing appears to be working because I can
ping the multicast address and get responses from the server on the other
network. I didn't think ping would work like that but as long as I have the
server process running I can ping the multicast IP and get a response. The
problem is my client app's packets do not appear to be reaching my server.
Is there something special I need to do to the client socket? I tried
SetSocketOption and adding it to the multicast group but that didn't help
either. It could be rras but ping worked. The SendTo executed without
error and sent the data out.
Thanks,
jim
