Unfortunately, IPsec doesn't directly support multicast traffic, so you
can't do what you want to do. The fix for site-to-site vpn configs is
to use GRE tunnels to carry the multicast traffic, but the Cisco client
doesn't do GRE, so that's not an option in this case.
Sorry I don't have better news for you.
