IIS 6 FTP login error

I setup a ftp server on windows 2003 where login in is integrated with AD.
ftp site works fine when I use lan address of the intranet. users can login
using AD username and password. no problem there.

Here is the problem. When user asscess the ftp site from the internet,
server verifies username and password but doesn't list files and folders and
hangs there.

Here is a log from cuteftp as the ftpclient:
150 Opening ASCII mode data connection for /bin/ls.
425 Can't open data connection.
Received 0 bytes, Abnormal termination
Can't close data transfer gracefully

I have router between internet and server and i have forward port 21 and 80
to the server 2003.

Any help??

Can you connect via ftp.exe ?
In ftp active mode, you need
inbound 21 and outbound 20
for passive mode, default port range is 1024-5000.
With w2k3 - you can customize it

so, make sure required ports are not blocked.
