VMG3925-B10B Multicast

Hello,

I have a problem with three multicasting devices not able to communicate via multicast when connected to Wifi on VMG3925-B10B. The devices are two Defa Power EV-charging stations and Defa Balancer -load balancing device. All the devices are connected to the router, they can be seen in the GUI. On router settings, LAN-LAN multicast is enabled, IMGP snooping is turned on. Multicast is set to normal mode, not blocking. When trying to pair the devices (make a multicast group with their own configuration app), in IMGP status screen on the router, those devices show up with their Filter mode as ”EXCLUDE”. I cannot find any setting to include these devices in a multicast group. Is there any more detailed settings for multicast? Or isn’t the router supporting multicast via Wifi? Can anyone help me with the problem? Thanks.
