FREE FIREWALLS

Internet, and other computers in the local network. Free for personal use.

ZoneAlarm is still free for personal
use but in crippled form. ZoneLabs produces a product full blown product called
ZoneAlarm plus. The plus versions supports many new features that won’t make
it into the cripple version like e-mail attachment protection, automatic trusted
printer and file sharing when you move your laptop between LAN's, advanced IP
blocking, ad blocking, popup-window protection, and more. Without email
proetction, the personal firewall cripple ware free version is pretty worthless.
The plus version is $39.95 or less - well worth the cost.

Linux Firewall Software
A firewall on Linux does not need to be installed so much as it needs to be activated. Linux has a feature called IP Masquerading built in that can allow the operating system to act as a NAT firewall and router for your entire network. NAT allows all the computers on your LAN to access the internet through a single Internet registered IP address on your Linux computer.
Linux supports packet filtering. A packter filtering personal firewall can check the packet type, source address, destination address, and port information to ensure all data packets follow a rule set. This is a very powerful type of firewall that is very transparent to the users on your LAN.. Here are a list of resources to help you configure your Linux computer as a firewall.

Micro Distributions:
There is also a movement on the Internet that is creating ‘micro’
distributions of Linux with all the firewall protection capabilities built in.
These micro-distributions can be run from a single 1.4Mb floppy disk and do not
require a hard drive! A simple 486 with two NIC’s and a floppy drive is
usually all that is required. Some of these firewalls can even be created and
setup under Windows so no Linux knowledge is necessary & can place all of
your computers behind a firewall.
