Multicast on the ASA

Unanswered Question

I have an ASA5505 with an inside, DMZ and outside interface. It also has configured a remote-access VPN for users to login to the inside.

Our customer has requested now that the multicast traffic that is being sent on the inside is able to go to the remote access VPN users.

I understand IPSEC does not forward multicast traffic and that there is a workaround of using GRE tunnels if this was a router, but does anyone know how to configure it with the ASA5505.

Any pointers would be useful?

I know ASA does not support GRE. But is there any workaround to make multicast traffic go through a remote-access VPN?

Other than turning multicast to unicast from the source (if possible) there is no other way around
