Simple question: i want to load two modules
/usr/sbin/modprobe ip_nat_ftp
/usr/sbin/modprobe ip_conntrack_ftp
I can put those lines in rc.local or use /etc/sysconfig/iptables-config But at reboot firewalld overwrite my choices and doesn't load modules Question : how to instructe firewalld to load those two modules?
Centos 7 uses systemd, so files named *.conf in /etc/modules-load.d/ can be used to configure which kernel modules are loaded at boot.
e.g.
echo ip_nat_ftp > /etc/modules-load.d/iptables.conf
echo ip_conntrack_ftp >> /etc/modules-load.d/iptables.conf
You can specify any options for those modules or blacklist unwanted modules using the usual /etc/modprobe.d/*.conf method.
See man 5 modules-load.d, man 5 modprobe.d and man 8 systemd-modules-load.service for more details.
PS: in debian and derivatives, you can just list them one-per-line in /etc/modules. /etc/modprobe.d/*.conf is also used to specify module options and blacklisting.
