FTP alternate port connection issues

Hi, my goal is to be able to access my My Book World Edition White Light remotely via FTP on a port other than the default 21.  Remote access is tested and works fine on port 21 (tested on my android phone on 3G) with my dynamic dns–namaurer.serveftp.com:21, but times out after accepting the user name and password of the My Book World when trying to connect on port 8000, the port I chose in the My Book UI as my alternative to 21.  I forwarded port 8000 to my My Book World private IP in my router (Netgear WNR2000v2) and thought I made the necessary exceptions for port 8000 in my Kaspersky firewall (maybe not).

Can anyone help me out?

Thanks!

Here is what FTPtest says when I try to connect to FTP through port 8000:

Warning: Selected port (8000) is not the default port (21) of the selected protocol.

This type of access is not supported, but maybe some of the other users can give you some advice. 

Thank you for your quick reply, Ichigo. Do you mean FTP access on alternative ports is not supported? I’m confused–why would the MyBook’s web configuration allow me to enable FTP and choose an alternative port other than the default 21 if that access is not supported?

Hi again, basically remote FTP access is not supported, this of course doesn’t mean that it wont work, but it is not guaranteed. You can check the following link for more information.
