Iptables Firewall Script / Tutorial

I wrote a simple little firewall tutorial/script that builds the firewall set as it teaches you about how to write rules. I know it's simple, but it's my first attempt at a tutorial. My own ruleset is much more complex and wouldn't make for good teaching material. Let me know if you have any suggestions or comments. Thanks.

Intresting.... sure you made it? I can sware I've seen that before..

I'm pretty sure. I started is yesterday on my train ride to work, worked on it some more on my way home, then finished it today, so I'm pretty sure it's mine.

Okay.. I jus thought I saw something very similar to it somewhere... Good Tut tho! :)

Can you read minds? I needed something like this THX! Great tutorial

I forgot to mention that after you run the script, you can make it permanent by running the command "service iptables save". This will store your ruleset in a system file and reload the ruleset every time the computer restarts.

Edit: Of course, this only applies in systems with the service command. I know RedHat uses it, and I think Mandrake might. If anyone knows of any other distros that use it, chime in.

*two thumbs up* keep it up d00d.. ur doing fyne. loookin gooood..
