Routing configuration

Dear People:

I want to configurate a linux firewall, my pc has two network cards,
I use whitebox distribution (RHEL ES 3.0 clon), and iptables.

My principal problem is when I configurate the iptables, How I to do
for block all incomming and outcoming traffic?

The idea is grant on demand access to internet and my LAN as need, I
don't like by default accept all the traffic but to filter it.

Thank's in advance for any hint.

Greetings,
Pablo

Read the IPtables-howto and twist the configuration to suit your
needs.

Change the policy to DROP:

iptables --policy INPUT DROP
iptables --policy OUTPUT DROP
iptables --policy FORWARD DROP
