I tried to set up a simple FTP server using IIS a couple of years ago, and it was an utter nightmare. Nothing worked. I pulled large tufts of lemur fur out of my head trying to get it to go live. In the end I found out that my ISP at the time (Time Warner Cable) was blocking me from initiating service, so it wasn't even Microsoft's fault.

Oh yeah, I was going to actually make a point, but i got lost in the painful memories. This is the thing: Almost all ISPs frown on you hosting a web site (or any server) through their connection. They usually provide a token amount of server space you can use on their hardware, but they may take all sorts of irritating steps to make hosting your own a hassle.
Yeah, it's been a bit of a pain getting things working; but on the plus side, I can now (pending final testing) bypass school filters using this computer
