Rules for UDP Broadcast Relay?

[pastic]

What firewall rules do I need to add so that the UDP Broadcast Relay package will work? I am interested in SSDP, so port 1900.

I want to relay between LAN (10.0.0.0/24) and OPT1 (10.0.1.0/24) interfaces.
But my phone on OPT1 (10.0.1.20) is not aware of the DNLA renderer on LAN (10.0.0.40). ("Notremusique" alias = 10.0.0.40)

SSDP broadcasts are successfully sent from 10.0.0.40 to 239.255.255.250:1900, and when the UDP Broadcast Relay is enabled I see a lot of return traffic (as in the screendump below) from the phone to the raspberry pi with the DNLA renderer, but still the renderer does not show up on the phone.

What am I missing?

This is so far working for me.
in this Case its 1900 SSDP and 5353 mDNS from my IOT_VLAN to LAN

This is well Documented by Netgate.

@jasch
Thanks.
I finally got around to try again. But to no avail. I allow everything through (any/any/any/any -you get the drift). It seems like both ends, music streamer on LAN and smartphone on OPT1, succeeds in passing multicast traffic to the multicast addresses. But the phone is still not aware of the streamer's existence unless I put them on the same subnet.
I think I have to give up. I am too much fumbling in the dark.
