(hint: netstat -nf > inet) That's true of "non-passive" mode connections (FTP server port 20 to FTP Client port 1024-65535), but I suspect the original poster is trying to permit passive mode connections. PS: does anyone know what the correct terminology for FTP's "non-passive" mode is? I sometimes refer to "active" mode when talking FTP (because that term somehow got stuck in my head once upon a time), but I usually get some very curious/confused looks when I talk about "active FTP"... :) Patrick.
