Yes.
That's why it's not a very good idea to run your own server except if you have special requirements, eg. Need lots of space, want to use PHP free of restrictions, etc.
Also, at 477 kb/s upload, users would download an average 4 MB song or other file in about 69 seconds (ONLY IF you were not doing anything else on the Internet and that user was the only one connected at that time).
477 kb/s upload speed is WAY too low to practically run a web server.
Plus, guessing from your questions and phrasing... I don't think someone of your mental calibre would be able to figure out how to start a server, open up a port etc. etc.
Stick with x10.
