setting up iptables with CentOS

[pauhn]

I want to write a quick script that will allow my server to route automatically (I'm testing this on a virtual machine). Would I put this:

while true
do
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables –A POSTROUTING –t nat –o eth0 –j MASQUERADE
done

in /etc/rc.d to do it automatically?

This would all depend on how you are booting. rc.3 is for CLI boot and rc.5 is for GUI boot.
Your best bet would be to look in /etc/sysconfig at the iptables file and edit it as needed.
