for a specific application, I need to route a multicast flow with IPSEC (we use a CISCO ASA 5508 firewall), I am not a network expert then I will try to explain as best as I can our issue I don't need any IGMP management everything is static:
- on eth_input we receive "multicast" messages (meaning that destination address is in the multicast range ex: 229.0.0.X
- on eth_output we need to forawrd these message in IPSEC message (defined by one IP public address for source and one IP public address for destination. On eth_output we disable IGMP
then basically the need is to forward statically the messages after encapsulation in IPSEC
On my side, I understand that multicast + IPSEC is not trivial, but I don't understand if this due to IGMP management only or not.
then my question:
- is the routing problem due to the fact that our destination is in the multicast range (then root cause there is a limitation in the firewall that reject the routing configuration) ?
- or is the routing problem due only to IGMP management with IPSEC (then in our case we will disable IGMP) ?
thanks very much for help
