Description

Having a TV provider with multicast streams, working flawless in 22.50 when upgraded to 23.01 it starts stuttering and stopped playing. After a research with packets captures it seems that the membership query from pfSense to the LAN devices is corrupted. Therefore the STB does not report back its currently joined groups, and the proxy sends out a leave on the WAN -> TV stops.

Screenshots with debugging showed here https://forum.netgate.com/topic/177181/23-01-b-20230106-0600-igmp-proxy-stops-tv-stream/31?_=1675500284303

I don't know if this is caused due to the IGMP-Proxy or the Intel 226v NIC driver running on an intel N5105 CPU.
