IPTV/igmp/multicast/udpxy issues

Description

I'd tried to configure udpxy
Installed it with opkg, and started with params:
udpxy -a 192.168.1.1 -p 34500 -m eth1.552
eth1.552 is iptv interface and has IP - 10.10.10.10
I saw that igmp membership report sent to eth1.552 when run tcpdump -i eth1.552, but did not see udp(multicast)
eth1.552 added to firewall IPTV_zone and added traffic rules in firewall config: allow IGMP input from IPTV_zone, allow UDP input from IPTV_zone and allow forward from IPTV_zone to lan(zone's name for br-lan)
It looks like bug, because even I turn off firewall , there is no udp(multicast). Possible kernel dropped UDP or network physical interface can't receive multicast or drop it
It reproduced on TP-LINK-WR841N v.9
