My new toy

I bought a LinkStation (250GB) yesterday. It's cool. I've centralized some of my data to this server, hence they are accessible from any machine within my LAN.

I tried to setup the FTP but no success. I can set up the FTP as anonymous FTP, but it is not accessible from the WWW (it said possible PASV port theft). If I set it up as restricted FTP (require LinkStation user login), the server is even not accessible (connection refused). I wonder what's wrong with it, or is it just me? :-S
