FTP works in a two-channel mode. One channel is used for commands, while the other is the data channel, where your files go through... Example of sockstat on the server, during an ftp connection COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS ftpd 55377 6 tcp4 192.168.1.6:21 =20 192.168.1.3:58121 ftpd 55377 9 tcp4 192.168.1.6:53808 =20 192.168.1.3:60020 As you can see, the first line is the command channel (local port 21 used), while the second line is the data channel (local port 53808 (could be any)). Your firewall accepts connections on port 21, but doesn't allow the data channel to be extabilished. Can you post the relevant lines in your firewall rules file? -- Pietro Cerutti <pietro.cerutti@gmail.com> Beansidhe - SwiSS Death / Thrash Metal <www.beansidhe.ch> Windows: "Where do you want to go today?"
