I want to be able to discover those devices by using SSDP, UPNP and WS Discovery, thus I have to implement multicast routing between the VLANs.
But here my doubts start:
- for WS-Discovery, the cient sends a probe and the devices answer with ProbeMatch. Is igmp proxy good for this? Should I put the interface in the 192.168.10.0/24 ad upstream, or the other one? I have traffic in both directions...
- do I need to enable IGMP snooping?
- do I need to add firewall rules to formward multicast between the VLANs or is igmp proxy enough?
I found the page about igmp proxy not clear enough.
Can you help me please?
