For ipchains (2.2.x kernels) I created a script in the /etc/rc.d/ directory and
chmod'd it so that it was executable.  Inside the script I used the commands
exactly like I would've typed them on the command line.  Then at the bottom of
the /etc/rc.d/rc.local I added a line that pointed to that script with the full
path to it, e.g. /etc/rc.d/rc.ipchains.
