GB-750 Firewall Appliance Product Guideiv 1 – Introduction 1
1 Introduction
GNAT Box Basics
Global Technology Associates, Inc., has been designing and building Internet
rewalls since 1994. In 1996, GTA developed the rst truly affordable
commercial-grade rewall, the GNAT Box®. Since then, ICSA-certied
GNAT Box System Software has become the engine that drives all GTA
rewall systems.
Powered by GNAT Box System Software, GTA's rewall systems currently
include the small-to-medium enterprise (SME) rewalls, GB-1500 and GB-
1200; the RoBoX line, for remote ofce/branch ofce applications, including
GB-750, GB-500, and GB-200; and GTA’s powerful software-based products.
Requirements
To connect the GB-750 Firewall Appliance, you will need:
• A power cord.
• Two Ethernet cables, one for each required network.
• A crossover cable to connect to a host or router, or a straight-through
cable to connect to a hub or switch.
A power cord, a yellow crossover cable and a grey straight-through cable,
as well as a null modem cable for the Console interface, are included with
rewall appliances.
In addition, to use GNAT Box System Software, you will need:
• An understanding of TCP/IP networking.
• Network IP addresses for all network interfaces used.
• Netmasks for each attached network.
• Default route for External Network.
• Which services to allow inbound (if any).
• Which services to restrict outbound (if any).
