Forwarding Sonos UDP broadcast to another interface

Is it possible to forward a broadcast traffic from one (bridged) interface to another (bridged) interface?

Here is an output from the firewall logging:

15:15:18 firewall,info input: in:br-ha out:(none), src-mac xx:xx:xx:xx:xx:xx, proto UDP, 10.11.12.2:3888->255.255.255.255:6969, len 108

This traffic is being generated from our Sonos audio system.
