Hey scty Library,
I forget your name.
I do not have an answer for your question exactly. However, I think I have a solution to the overall problem, and it is here:
http://www.lowth.com/LinWiz/1.09/
I use the wizards to create my iptables files. I have a couple of basic files that I use, and then I tweek the appropriate one after copying it to a new install.
For people who want a solution fast, the two wizards are great.
I hope this helps.

it works so that I can build my self a

and mabey a VPN. Anyway I tried to use a command on
my
Desktop CentOS3 machine.
"iptables -A INPUT -s 127.0.0.1 -p icmp -j DROP"
now the command seems to have went through because I didn't get any errors, but when I go to ping
127.0.0.1
I am getting a response and my packet loss is 0%. It should be 100% packet loss.
Can anyone tell me what I am doing wrong. I am not trying to do anything yet, just want to learn by exploring.
