Server Help

SO i tried making a Dedicated Server by following these instructions: http://www.youtube.com/watch?v=xyzhMwJ6Q6I
so far everything works fine except for the ports :confused: I know this has been posted before but i have tried a TON of ports and none work. Either its me putting them in wrong or i have the wrong ports. Here is a link to a picture of my routers port forwarding page (cause i don’t know how to put them on this post :D):http://www.flickr.com/photos/55003500@N08/5090171791/
