Hi !
This may be quite basic for some of you. I'm using my own firewall script on a Suse 8.2P box. See below. Clients can connect and login but when a command like LS or GET is given, nothing happens. It seems data transfer is not possible. It doesn't make a difference whether passive mode is used or not.
--> Maybe http://slacksite.com/other/ftp.html helps to understand the FTP protocol. When using passive ftp, you have to allow connections to all high-ports on the server. For active FTP, it's port 20 and 21 on the server but many ports on the client. Neither solution is really nice. Have you thought about using scp/sftp (there are nice clients for Linux and Windows) which is much easier for firewalling (you only need port 22).
