THIS IS OLD. USE IPTABLES NOW.
Debian Packages: bastille.
A firewall can be set up on a machine connected to the Internet and
can then relay network traffic to machines connected on a local
network.
The bastille
package provides both a firewall and Network
Address Translation (NAT--also referred to as IP
Masquerading). When installing the
package use the defaults and all should be just fine.
