Again: 192.168.0.24 is shown in the dropdown list "select one:". That means, this IP is assigned to the PC as well and you can't use it for the Dreambox.
Just use any other free IP for the Dreambox (192.168.0.11 for example).
When booting via DreamUp the Box does not use any internal settings from the firmware - it will use the IP you enter in "Remote IP (Box)"
