Thx for your quick answers. Could it be so simple that this can't be done with my router D-LINK 624?
For other applications it is enough to do a port forward for only one port and that is done on "virtual server" se picture 1

I'm not sure if it is possible to forward a range of port, I have tried on "application" with no success
