FTP over SSL is an entirely different beast. I do not think that this will work. We call know that FTP uses separate TCP connections for data transfer. To have FTP work through a firewall, especially one doing NAT, the firewall has to not only be able to read the command channel, but it has to be able to modify it. Obviously, if your command channel is encrypted, the firewall can do neither of these things. -- Crist J.
