Arduino sending UDP messages,,,, dont work after 100bytes, wireshark help

This is a challenge if you plan on sending zero bytes. It will stop at the first zero byte. It transmits a zero terminated string.

    Udp.beginPacket(remote_ip, remote_port);
   Udp.write(ReplyBuffer);      
       Udp.endPacket();

If you want to send zero bytes, you need something like this:

    Udp.beginPacket(remote_ip, remote_port);
   Udp.write(ReplyBuffer,20);      
       Udp.endPacket();

This sends 20 bytes, zeros and all.
