Yes, it looks like FC's default firewall does not
support the concept of "inbound" and "outbound". For
FTP I think part of the problem is the concept of
"active" connections-- see
http://slacksite.com/other/ftp.html for a good
technical description. Altas, unless you are willing
to muck around with your system by installing a more
advanced firewall GUI (firestarter might work-
http://www.fs-security.com) or are willing to do it
hacker style (iptables) I do not think the FC suite
gives you an easy option to just enable "outbound"
You might just have to risk the slightly increased
security risk of enabling FTP in the firewall and
making sure you are not running any ftpd (ftp server)
in system-config-services. Basically a hacker would
already have to have your system compromised to set up
an ftpd so the added risk of enabling FTP in the
firewall is minimal.
