I have 2 networks
Network A - 172.16.1.0/24
Network B - 172.17.1.0/24
On Network A I have a device (172.16.1.200) that listens for messages to the multicast address (specifically 224.0.1.75). This device does not use IGMP to join this group.
On Network B I have dynamic devices which send messages to this same multicast address (224.0.1.75), and also do not use IGMP to join the group.
I want to forward all packets destined to 224.0.1.75 from Network B to Network A.
Since IGMP is not used, I don’t think I can use PIM or IGMP proxy to accomplish this.
I can see the packets hitting the prerouting and dst-nat chains of the firewall.
I’ve tried adding a mangle rule that increases TTL, as well as adding a static route for 224.0.1.75/32 with the network A interface as the gateway, but nothing gets forwarded.
Am I on the right track, or is this simply not possible to do with routeros?
