I just said that because when I was enabling FTP on my server and thru the firewall, I opened port 20. Course I listened to dj_goku and that may have been mistake number 1. ;-) (We just love to bag on dj_goku.)

Actually, you probably need a ftp tracking module installed into the
kernel; ftp has two ports, the command and data port. The command port
is 21, which does things like initiate transfers and list directory
contents, etc. It also sends a random number which pertains to the
port number for the data port. Now that I think of it, this usually
matters much more for the clients, I'm not so sure of the server.
Anyone wiser than I (it isn't hard)?
