Endian Firewall has a Enterprise edition and a community supported opensource edition. The Enterprise edition comes in both Appliance as well as a software edition which allows the enterprise admins to install Endian on their own hardware.
Endian Opensource free edition on the other hand is available as a ISO download and can be installed on even an old PC. Ofcourse, with multiple modules running needs may vary on the hardware. For instance, if you need to run the proxy module then the disk needs to have enough space for caching.
Installation is very straight forward, burn the ISO image on to a CD and boot with the CD-ROM and follow the onscreen instructions to complete the installation. Once installed, browse to the http://x.x.x.x where x.x.x.x is the IP address of the trust (green) interface. Once there, a wizard starts configuring the admin passwords, network interfaces for various zones (Orange for Wireless, Blue for DMZ, RED for Untrust or Internet facing interface like ISDN, ADSL).
Endian website has a great documentation and a good FAQ to support a good opensource firewall. For more information, documentations and download, click here for Endian Homepage.
