Trying to send multicast across a vpn. I'm familiar with IOS support for GRE tunnels which would in turn be tunneled in ipsec by the same router or a pix. Does ASA support GRE tunnels and GRE tunneled in ipsec?
As best I recall, ASA will not encapsulate into GRE.
ASA can encapsulate GRE packets, along with any other type of IP packet.
If you are trying to send multicast, then you might want to use a layer 2 transparent VPN, which I seem to recall seeing that the ASA supports (but I haven't studied the facilities of the relevant software releases.)
