    You are sending to 172.16.100.4 from the DHCP4 server, but listening
    on localhost on the DDNS server:<br>

    You need to listen on your global IP address. Use <font
      face="Courier New">ss</font> or <font face="Courier New">netstat</font>
    (if you have them available in your container) to confirm which
    interface D2 is actually listening on.<br>
