Getting FTP access to my computer from outside my Network

[shea]

Hi,
I'm a college student and I have an IBook G4 which connects to the internet wirelessly via a wireless modem in another room which is connected up to a cable modem which is always on. I have managed to set up ftp access for computers whithin my closed network, so my ftp address goes something like ftp://192.168.0.x
My question is: how do I set up my computer so that I can get ftp access to it from outside my network. For example if I'm in a computer lab and i need to retieve a file off my computer I want my computer set up so that i can access either an http website which has an index of a specific folder on my computer or so that i can access a folder directly via ftp.
I have done this using apache and php on a windows computer but it was a long time ago and i've forgotten how i did it.
Thanks, any help would be usefull.

1. Get a free dns account at no-ip.org, create a hostname (e.g. mycoolmac.no-ip.org) and make sure it points to your external IP.

2. Download their OS X update client; that way the hostname is updated when your IP is. Not that you will have to keep this open and scheduled to update as often as you like so you'll always be able to connect.

3. Make sure you have your mac's firewall open for FTP access. Make sure your router is configured to allow FTP access and that it points to your mac.

Shouldn't have any problems this way.
