I know that IPSec doesn't support multicast, but L2TP over IPSec does. My current scenario is:
In the corporation internal net, every node can send and receive multicast data without problems. Now we want to make the VPN clients receive multicast using a PIX (8.0.4) firewall. So far, the clients can connect to the firewall by L2TP/IPsec and get an ip from intranet, and normal routing works well.
But multicast doesn't work. I have tried all the options related to IGMP and PIM in PIX.
Can somebody tell me whether it can work this way.
Thanks
