FTP Access

Oi i'm such a noob at this....

How do I share my Apache WebServer over the internet? On my old OS, Panther, i had it setup and i could access files off of my DynDNS site, electricman5.servebbs.com. But now, even though I have the DynDNS Updater, whenever I go to to the site, it can't connect to the server. It automatically updates it too my external IP, but my Internal one works fine, and lets me go to the server.

So how do i make a server, that lets me share files in the FTP format off a webbrowser, that can be accessed by anyone online, not just on my network?

i'm a real noob at this... Anything will help

 

like ftp://ibiblio.com

So that anyone can access it
