Hi folks.

We have a wired network that has a utility the broadcasts udp, and clients pick up the heartbeat and attach. It works fine on the wired, and we can see udp packets. However, we don't see any udp on the wifi.

I have enabled broadcast forwarding without success. Can anyone suggest a fix ?

Many thanks,

You would need to either enable multicast-unicast on the WLC or the more preferred method would be to enable multicast-multicast on the WLC under CONTROLLER>General.  Unicast is a lot of overhead on the WLC as the WLC has to replicate the packet for every AP that is joined to it.  With multicast, you have to multicast routing on the network and PIM enabled on the WLC management interface VLAN, the AP VLAN(s), and the client VLAN(s).
