i've downloaded the .jar server software file from minecraft.net and it seems to be running fine, but i went to whatsmyip.org and used the ip it said was mine to try and connect, it doesn't let me. I can connect to the server with localhost but i can't connect with the ip. My computer is connected with a router. Also, each time i start up the server, it says setting up spawn area, and it doesnt seem like that should happen every time, maybe i'm wrong. Any help would be appreciated....
