IPCHAINS
This assumes that your external interface is called `ppp0'. Use ifconfig to find out, and adjust to taste.
# ipchains -P forward DENY
# ipchains -A forward -i ppp0 -j MASQ
# echo 1 > /proc/sys/net/ipv4/ip_forward

IPTABLES
http://en.tldp.org/HOWTO....TRONGER

that link will take you to a howto for IPTABLES

look for:

#CRITICAL:  Enable IP forwarding since it is disabled by default since
#
#           Redhat Users:  you may try changing the options in
#                          /etc/sysconfig/network from:
#
#                       FORWARD_IPV4=false
#                             to
#                       FORWARD_IPV4=true
#
echo "  Enabling forwarding.."
echo "1" > /proc/sys/net/ipv4/ip_forward

if you pay close attention to the directions its quite possible to turn linux into a router and firewall. you could buy one, or you could save money but not time and configure it manually.

Why do all that?!?!?!

Just get the iptables.dsl and rc.firewall.dsl
http://projectfiles.com/firewall/
http://projectfiles.com/firewall/config.html

Then if you are using "frugal" mode just edit the rc.local file...

It is a simple script, but is capable of doing tons upon tons of stuff..internet sharing, port forwarding, routing, you name it..with just a few simple script modifications you could make a small DSL machine into one hell of a powerful router/firewall...

or you could build you a SmoothWall Express 2.0 box
