Change src ip address for IGMP packets

RouterOS Forwarding Protocols
1

Hi all,
I trying to change src ip address of my TVBox located in LAN (192.168.1.1/24) to my Mikrotik WAN address (10.10.10.25/24) for all outgoing IGMP packets.
I have configured NAT masquerade, it works for regular unicast traffic but not for IGMP multicast trafic like join or leave messages.

Could you help ?

You should never NAT IGMP traffic, use IGMP Proxy instead.
