Y U NO LET PEOPLE PLAY ON YOUR SERVER?!?!?!?!?!?!? lol jkjk

I had the same problem until about a week ago. you obviously need port forwarding. if you don't know how to forward ports, i can start you out by saying that you can type your IP address into the top of your browser. from there, im lost since i have a mac :|
