I only have one real world address.  So I am running Network address
Translation.  I set up a FTP server internally with a 10.*.*.* address.  On
the router, I set it to redirect all traffic on port 21 to the proper
internal 10.*.*.* address.  Externally when I try and connect to the FTP
server.  I am able to connect, it processes my username and password, but
then it will not let me upload or download files.  It also will not give me
a directory list.  I can change directorys, I just can not do anything else
on the FTP server.  If I connect in passive mode, it authenticates me and
then tries to switch to the 10.*.*.* address with the random port number.
Any ideas on how to work around this would be greatly appreciated.

Thanks
