What ports have you opened and how exactly (Just making sure you have correctly opened the right ports)?
What port does your minecraft server listen to (See server.properties file).

You'll need to give him your "external" network address, visit a website such as http://myip.nl/ to view your ip.

Yeah that's not the right ip. Google 'what's my IP' and it'll display the one you want.
