Allow multicast between two NIC's / IP Ranges.

[TomT]

Hi,

My OPNsense is currently configured with multiple interfaces, I need to allow multicast between two of them.

LAN  192.168.1.x
OPT1 10.10.10.x ( wifi )

Routing of traffic between these interfaces is working well, but I have devices in both ranges that send and receive multicast so I need this to pass between the two.

Ideally I'd like to specify what multicast IP addresses and ports are allowed, but it's not an issue if I have to allow all multicast.

Can someone advise how to do this, or are there any guides on how to set this up.

Thanks.

You need os-mdns-repeater, udpbroadcastrelay, avahi or whatever... depending on use case.

Thanks.

I think udpbroadcastrelay may be what I need.
I'll install it an see how I get on.
