I'll have a look at firewall settings. As far as I know port 21 is blocked. Strange
Most firewalls are configured to block _incoming_ traffic. Not many default system configurations block _outbound_ traffic and I can't remember a time I ever loaded a version of Fedora whose default firewall configuration does. The data you provided earlier shows you are using an unprivileged local port (60088) to connect to a remote IP address using a reserved port (21). Unless you have specifically blocked all outbound traffic from your system to external FTP servers, this connection will not be blocked.
This is the same kind of situation that occurs every time you connect to a remote web server with a local web browser. Your system uses an unprivileged port locally to connect to the remote IP address and port 80 (or 443 if you're using SSL). Note that the reverse is completely different. Ports 80 and 443 are most certainly blocked by default with respect to remote systems trying to connect to your local web server.
