IGMP configuration on DR6410

Has anyone got any experience of enabling IGMP over a cellular link?

I have two DR6410 routers connected to an APN with a GRE over IPSEC tunnel between them. I have configured both static and multicast routes and am able to talk to devices or manually send a stream of multicast traffic across the link. However I can’t get IGMP packets across the network to initiate the stream correctly.

I have enabled IGMP on the ETH, GRE and PPP interfaces that are in use but am having no luck.

Any ideas? Thanks in advance for any help

Have you setup IGMP forwarding as per page 185 of the refrence manual
