Multicast Forwarding issues

We have recently set up Multicast forwarding between our main office and a remote location via a site-to-site vpn.

The Multicast forwarding is working from the remote location back to the main office, however, the system we need to multicast in the opposite direction cannot do so.

In the firewall logs at the main office, we are seeing the following:

And the traffic is not traversing the VPN as it should to the remote location.

I have static routes set up for the multicast traffic on both sides properly.

We are not seeing this denied messages on the remote firewall.

  • I did have multicast routes on both ends to accommodate for the multicast traffic in both directions, but that did not seem to help.

    For example, the two systems I need to have bidirectional communication between them are (Main site) and (Remote site)

    The Multicast routes were as follows:


    Source  IP         Multicast IP    Source Interface  Destination Interface        Port 1                   IPSec Connection        RemoteIPSec      Port 1

    Remote      MainIPSec               Port 1       Port 1                      IPSec Connection
