I assume your trying to host a dedicated server. Try downloading LogMeIn Hamachi. It's like a VPN (Virtual Private Network). All you need to do is tell your friends that you want to play with to download it. Then join your Hamachi network. Then change the server IP address (in your server config file) to what your IPv4 is.
