Your confused with two IP addresses. You can NOT use that NAT IP address, like 192.168.0.1 You need to give your friends your PUBLIC address. That is what is supposed to be. That NAT address is really hidden from the Internet. Meaning NOBODY can see your IP address that is why your not able to located by your friends.
