There are numerous walkthroughs and tutorials on this, I'm surprised you couldn't find something.
1) dump your web content (HTML files, images, etc.) into /Library/WebServer/Documents
2) Configure your router to forward connections on port 80 to your server (the specifics will vary depending on your router make/model)
3) Use GoDaddy's web portal to setup www.g4uoc.com to map to your router's public address.
You're done. Remote users will lookup www.g4uoc.com on GoDaddy's servers and will get your router's public address. When they try to connect the router will forward the connection to your server which will serve the matching request from /Library/WebServer/Documents/
Wow, thanks for the awesome and quick response. I'm honestly surprised it is that easy. I do have my router's port 80 forwarded, The part I am stuck at is Godaddy's horrible web portal design.
I am guessing that I have to go to their DNS Management page and then have it set up to point to the routers IP like you said, but the only option I have is to add an "off-site" DNS. Is says add a domain name but then I go to add "g4uoc.com" to it, is says "Domain name already exists in private label." And if I add the outside ip address is says "Invalid domain extension." I think I am missing something here. Sorry for the trouble. I just really am confused with this poor design of their web portal. Thanks for all the help thus far though, I really do appreciate it.
