wan - lan bridge multicast

[elmati]

Hi. I've connected router lan to my pfsense 2.6 wan witch static ip.
I want to do a simple bridge to pass multicast traffic "wan-opt1" being opt1 a physical interface.
I thought that, only bridging and any - any firewall rule was enough to pass all traffic if pc is asking for multicast udp packets.
But i cannot pass these packets. Do i really need igmp proxy to do that?
Thank you

ont - Asus rt-ac68u -> untagged packets and multicast -> pfsense (wan) -> stb or pc (opt1)
Don't mind security in this interface.

You also need to enable IP Options on the pass rules:
