    Can someone please help me. I can not seem to find a way to modify for UDP or TCP packets the dst or src ports. Are they always zero?

    Hi George,

    Are you talking about Packet Builder?

    If you cannot change the port number in Decode Editor, you can directly input port number under Hex Editor:

    Highlight the Source Port item in Decode Editor, and you will see the hex digits are highlighted too in Hex Editor.
