If you were looking for a separate firewall box, rather than using a software firewall on your workstation box, which will slow it down slightly, there are many options. You can buy firewalls from network hardware suppliers such as Cisco, or you can set up an old computer as a linuux firewall eitherusing your own customised linux, or using a linux firewall distribution such as SmoothWall (www.smoothwall.org)
