People still can't connect to my bukkit server...?

So a few months ago, on the day my server was opening to the public, my server stopped working. I'm not sure what made it stop working. By it not working, I mean people can't connect to it. The ip didn't change, I've already made sure it's still the same. I'm almost 100% sure I port forwarded correctly. Here is a screen shot for people to look at to be sure:


Anyways, I made a separate folder for run.bat and craftbukkit.jar. I 0pened the console and when I was done loading, people couldn't connect. The server couldn't be reached. Before, I usually got some kind of message that said:
<insert random ip here> lost connection
but I don't even get those anymore.

Does anyone know how to fix this problem? My server was running before, and this just randomly happened. This did happen on the day 1.6.4 servers weren't working for many people. Mine still doesn't work, and I updated to the latest version of craftbukkit(1.7.2).

bump~

Is it your Computer Firewall blocking the port?

That usually the issue

How would I know if it's blocking the port?

 

Before i even find out about craftbukkit i was setting firewall off,because my friend was telling me that and it worked!But i turned the firewall on and it still works

 

Sorry about late reply. Are you using Windows or Linuxs?
