hello,
i try to setup igmp proxy with no success 
i have rb600 with RouterOS 4.2 and ether1 is iptv interface and ether2 local interface.
when i make bridge with ether1 and ether2, iptv works fine. With igmp proxy nothing works.
There is always these errors in logs:
Leave multicast group failed on ether1 group=233.33.210.7:
Cannot assign requested address.
Btw I can see multicast traffic in igmp proxy menu (RX/TX increasing).
What is wrong?
Please help.
