I am experiencing one issue on ASA 5520 firewall with version 8.2(2). There is a Server in LAN which sends the multicast traffic to DMZ network where in NAT is given for hiding real ip of DMZ server and further it forwards the multicast traffic to its clients at outside interface.
The issue is about multicast traffic not traversing from LAN interface to DMZ network. Eventhough we have allowed nonat entries from Sender and multicast ip, the traffic is not passing through at all. We have verified multicast routing is enabled on asa firewall and see the packet sent and receive response.
Can anyone let me know the reason of blocking the multicast traffic from one interface to other interface
