FTP server PASV problem

[canadian4evr]

Hey guys,

Just having a problem with my home ftp server. For some reason every time I try to connect to the server it pauses for about a minute or so and then disconnects. Here is my FTP client log:

Then it freezes at this point... and then eventually I get this:

[02:50:21] An established connection was aborted by the software in your host machine.
[02:50:22] Server closed connection

Anyone who wants to give me a hand can test it out themselves, there is an anonymous user account setup that shows the exact same problems as a registered user (no files in the directory though) ftp://cdn.mine.nu/ chances are the connection will time out though so

The server is setup as a DMZ IP under the router. There is no firewall software loaded on the server. It is running Windows Media Centre Edition 2005 with all updates. Windows firewall also turned off, with zone alarm pro installed.

Thanks =)
