rc.firewall.txt

The rc.firewall.txt script is the main core on which the rest of the scripts are based upon. The rc.firewall file chapter should explain every detail in the script most thoroughly. Mainly it was written for a dual homed network. For example, where you have one LAN and one Internet Connection. This script also makes the assumption that you have a static IP to the Internet, and hence don't use DHCP, PPP, SLIP or some other protocol that assigns you an IP automatically. If you are looking for a script that will work with those setups, please take a closer look at the rc.DHCP.firewall.txt script.

The rc.firewall.txt script requires the following options to be compiled statically to the kernel, or as modules. Without one or more of these, the script will become more or less flawed since parts of the script's required functionalities will be unusable. As you change the script you use, you could possibly need more options to be compiled into your kernel depending on what you want to use.
