The reason you're having a connection problem is because the IP you gave was a local IP, not the external. You probably also did not forward port 25565.
If you're having trouble I might throw something up since my computer's set up to host a Minecraft server.
Alright dude you know what, if you wanna host that's fine. Just set up a time and post here and stuff.
Windows Vista doesn't want to let me open ports. 
Thanks man.
Alright, cool beans. THIS SHIT'LL BE POPPING NEXT WEEK.
