All of you seem to be having the same problem.  I once did some 
research on the FTP protocol for use in a script I was writing, so I 
know enough to be able to tell what's going on.

FTP connections require more than one socket connection.  You 
have the main connection that you initiate with the server, a 
connection that the server uses to send files to you, and a 
connection that you use to send files to the server.  The problem 
you people are experiencing seems to be happening when the 
server tries to make the connection to send files to you (a directory 
list is a file, by the way).  It is my understanding that STN 
intercepts these commands and sets up a port that will forward to 
your internal client machine behind the STN box.  Apparently it is 
not working right for some of you.
