MCServer listens for connections on all available interfaces, so there's no need to specify an IP address.
Just to be sure, your friend isn't using "localhost" as the server address, right? That won't work, because his "localhost" is his machine, which doesn't have the server running; he needs to type in your computer's IP address or hostname (if available).
If you're on Windows, open command prompt and type "netstat -na" to verify that your server is indeed listening on the ports. You can also use "ipconfig /all" to find out your IP address.
If your friend is not in the same network as you are, you will need to configure your router's NAT to forward MCServer's port to your computer. I can't help you with that, because that's very specific to the model of the router.
