[Zope] Zope FTP Hang File List Problem

[hpinson@indepthl.com]

Hi Dieter.  Yes, we have tried both passive and non passive FTP.  In either 
case, according to the Z2.log we get enter Zope successfully, but the 
session appears to hang on the FTP "LIST" command.  No files or 
directories are visible.

Several folks have pointed to NAT problems, but why this problem would 
only show up only at the "LIST" request does not make sense to me.

Here's the whole Z2.log entry:

==> 220  FTP server (Medusa Async V1.18 [experimental]) ready.
<== USER *****
==> 331 Password required.
<== PASS <password>
==> 230 Login successful.
<== PWD
==> 257 "/" is the current directory.
<== SYST
==> 215 UNIX Type: L8
<== PORT 10,0,0,6,4,13
==> 200 PORT command successful.
<== LIST
==> 150 Opening ASCII mode data connection for file list

... Session hangs and will not list directories or files.
