Firewalls
A firewall is a hardware or software solution to enforce security policies. In the physical security analogy, a firewall is equivalent to a door lock on a perimeter door or on a door to a room inside of the building - it permits only authorized users such as those with a key or access card to enter. A firewall has built-in filters that can disallow unauthorized or potentially dangerous material from entering the system. It also logs attempted intrusions.

FREESCO
FREESCO was developed in the open source tradition as an alternative to routing products offered by Cisco, 3-Com, Accend, Nortel etc. While all of these companies offer products that are well made, the overhead and overall costs can be expensive.
FREESCO is open source, stable, inexpensive, easy to use, extremely versatile and flexible ... and best of all, FREESCO is FREE.
FREESCO is based on the Linux operating system. And incorporates many of the features of other Linux distributions into software that fits onto a single 1.44 meg floppy diskette. With FREESCO, you can configure:
