UDP Broadcast across VLANs

[rlebeau]

Yes but when I use the same IP on both sides client and server nothing is being sent. Am I missing something?

I can't answer that without knowing your actual network config and socket setup. But in general, the receiver needs to bind to a local IP/port interface for listening, and then subscribe to the multicast group IP using that interface. Then the sender can send UDP packets to the group IP.
