I can respect that. I come from a background of Windows Server administration and hence have some sort of point of reference in regards to what damage root access can lead too. I wouldn't go this direction unless I felt like I had too, but I'm having a ton of issues getting this VPN service to work and I found a configuration file that appears to have the incorrect information in it, so I was going to attempt to edit it manually.
The file I'm referring to is "com.apple.RemoteAccessServers.plist" located in "/Library/Preferences/SystemConfiguration".
Also, most of these guides are alluding to an "edit" button that I don't see. I'm not sure if it's a version difference or what, but I can't find what they're referring to. Are you familiar with this? It might just be an obvious thing that I'm overlooking.
