Unicast to multicast

Hi all !

I have RB951Ui-2nD. I need to make forwarding unicast traffic from external network to multicast address in internal network.

External network on ether1 192.0.1.130 (net mask 192.0.1.0/24)
Internal network on ether2 - ether5 192.168.190.0/24
Multicast address 239.0.2.1

I tried make dstnat rule to translate unicast to multicast and use IGMP proxy. But I have not success :frowning:

Please help me to setup my Mikrotik.

Thanks in advance!
