Firewall config and ftp server

[Edward S.P. Leong]

Dear All,

Our is fedora 11...

How can we enable the following of firewall function ( modules ), then
the ftp server is good for working ?

modprobe ip_tables
modprobe ip_nat_ftp
modprobe ip_conntrack
modprobe ip_conntrack_ftp

Due to trying the following cmd under fc 11:

[~]# modprobe ip_tables
WARNING: Deprecated config file /etc/modprobe.conf, all config files
belong into /etc/modprobe.d/.
FATAL: Module ip_tables not found.
[~]#

Thanka !

Edward.
