Introduction to BrazilFW

BrazilFW is a Linux Firewall and router that runs on older standard PC hardware. The older hardware BrazilFW runs on is stil several times as powerful as commercial small/home office firewall products.

The main purposes of BrazilFW are:
-Sharing a broadband Internet connection.
-Providing firewall protection to the PCs connected to the BrazilFW.

BrazilFW Requirements

BrazilFW runs in any old 486 with at least 16Mb of RAM. You do not need a HD, as it fits to a single floppy but you can use one if you wish to. If you install the system to a HD it will boot faster and you can add some advanced functions like Http cache.

To get a working network with BrazilFW, you need to have an Internet connection, a switch/hub/access point, and the appropriate Ethernet cabling to connect everything.

Also, you need to think about what ports and protocols you want to be passed through from the Internet.

BrazilFW is based on the former Coyote Linux floppy firewall/routing system.
