Receiving problems of W5300 UDP broadcast

W5300 configuration:

I have tested the router accessing to the same network segment, and I have also tested the direct connection with the computer. They are unicast and broadcast.
But can’t.
Ping is not offline in the whole process.

I also didn’t receive a response from the PC tool(cmd), but I received a reply from a network tool called wireshark(freeware). Please download the tool and check it out.
