Iptables setup

[Chris Peterman]

Well, what I have doen on all my boxes (regardless of distro) is to make out 
the iptables rules then do "iptables-save > /etc/somefile (replace "somefile" 
with your name of choice, I like "iptables-up-rules")

Then in /etc/network/interfaces, below the eth0 (or whatever your interface 
is) I put "pre-up iptables-restore < /etc/somefile" (again replace somefile 
with whatever you named your file) This loads the iptables rules as the 
interface is coming up. Anytime you modfiy your rules just do "iptables-save 
> /etc/somefile" and next time you reboot..

Also its important to use > and not >>. We want to clobber the file this time, 
NOT append to it! :D
