Aug 29, 2008 · IPsec was created to be a security protocol between two and only two devices, so a service such as multicast is problematic. An IPsec peer encrypts a packet so that only one other IPsec peer can successfully perform the de-encryption. IPmc is not compatible with this mode of operation.

The usual IPSec Site-to-Site tunnel can not do this. The VTI interface can transmit multicast traffic in a VPN tunnel. (VIT interface must use site-to-site VPN) 1. Select "VPN Tunnel Interface" for the VPN connection 2. Go to Configuration> Network> Interface> VTI> click on Add VTI interface. It has support for IGMP (multicast) function. KB-00176

Jan 04, 2006 · The current method for solving this problem is to use generic routing encapsulation (GRE) tunnels in combination with IPsec encryption. GRE tunnels do support transporting IP multicast and broadcast packets to the other end of the GRE tunnel. The GRE tunnel packet is an IP unicast packet, so the GRE packet can be encrypted using IPsec.
