We have a RUT-955
We are using the cellular WAN connection, and using openVPN to connect back to a remote network
The local LAN contains a multicast video source
Ideally, we would only stream multicast traffic over the cellular link when there is at least one consumer of the multicst group on the remote network. I think that for this to work, we would need to make use of PIM-SM on the Teltonika device
Given the Teltonika units are based on openWRT, it seems this might be possible...but I can't find any reference to whether it has actually been implemented on any of their products. Does anyone here have any idea?
