Hi Larry,

A lot of this stuff is in the RHEL Administrator guides. They're good
reads and provided to you free (download from RH's site), to help you
understand the workings of RHEL. These docs also clear up many questions
you'll have in the future administering a RHEL machine.

I personally don't use specific rules like that (I use shorewall
firewall), but from memory you have to use the command:

iptables-save

To save the iptables rules into a file, which will then be used on boot.

Regards,

Michael.

Do I need to put the line below in a startup script or did it just add
it permanently to my iptable rules?
