Can't connect to server

I just set up my server, using WorldEdit, WorldGuard, PEX, War, and Essentials to make a small server for me and a few friends. I just set it up, and when using 'localhost' as the connection IP, I can access it just fine. However, when I tried my local IP or my Public IP, I can't connect for the reason, 'java.net.SocketException: Permission Denied'

Heres my server.properties:

#Minecraft server properties

level-name=world
enable-query=false
allow-flight=true

Anyone know why I can't connect to my server? O_O

Firewall maybe?

 

I tried connecting, and disabled the firewall; still got the same error.
