Question on insmod module being dropped.



I've run into a problem with the ip_conntract_ftp and ip_nat_ftp 
modules being dropped. I've got a script that adds this called from 
rc.local, and it works fine, but the later the modules disappear. 

The script has the following lines and works fine.
insmod ip_conntrack_ftp
insmod ip_nat_ftp


Here is a lsmod list, and it shows the modules loaded, but later, both 
disappear. They don't have the autoclean, but further down the 
iptable_nat and ip_conntrack include these and the autoclean. After 
a while, these would diappear from the top, and from the iptable_nat 
and the ip_conntrack which do have the autoclean. This machine 
has 9 ethernet ports, with one connected to the backbone, and 8 
others going to individual labs. (Planned) 

Is there a way to have these modules loaded so they will not be 
dropped. Currently I've added a cron option to reload every minute 
since the auto clean talkes about the time being about 1 minute. 
This is Fedora Core 1 with the 2.188 kernel.
