StucK on DNAT for my Minecraft Server. Need a guru.

I reviewed many many posts and I am not getting past this. Can someone look and tell me where I missed?

Can you look at the images and tell what I got wrong?

Thanks!!

Yes, sophos creates the automatically the right range for source-ports. You only need to enter the destination port. Have an look on the predefined services ;-)
