Ok first off all check if your ports are open on server port 7777!
If not please look at this website: http://portforward.com/
Here are the basics for every router that can portfoward.

Then when you opened port 7777 Open server.exe.
Then it's loads the gamemode.

When done you go to http://www.watismijnip.nl/ and give them the numbers like with xxx.xxx.xxx.xx:7777

And they can connect to your server.
When not you did something rong with portforwarding!
