Firewall Setup

[devil505 at hawaii.rr.com]

Well I took Warren suggestion on the firewall.  I loaded Red Hat 7.1 (everthing).
 I downloaded the Mon Motha script, and made the changes to iptable, inet_iface,
lan_iface, and to enable.  when I moved the file to the /etc/rc.d/.  I also
seutp my TCP/IP config to what is in the instructions.  when I ran the rc file
I had a lot of errors

Perhaps iptables or your kernel needs to be upgraded.

Then when I ran iptables -L I received the following

-- snip

So at this point I am not sure if I did something wrong or not.

Help is greatly appreciated.
