If you followed the accompanied readme to the letter, you only need to open up the WebAdmin interface, once your server is online.
First of, go to the Beta_Dedicated_Server.ini file and look for "ListenPort". There you can assign the port for the WebAdmin. I recommend using a number that is two or three higher than the actual Serverport (7777 by default), so for example: 7780.
Then all you need to do is go to http://SERVERIP:LISTENPORT/ServerAdmin/
In your case, unless I am mistaken, this would make for:
http://68.96.100.228:7780/ServerAdmin
This should make a login window pop up, in which you need to enter your admin login details, as if you were to login in game.
Let me know if it worked.
