How can I configure an inexpensive firewall for my company?
There are a wide variety of firewalls available today. Perhaps the most basic firewall is the personal PC firewall, such as that built into Windows XP. Next come more advanced PC software firewalls, like ZoneAlarm Pro or BlackICE. There are midrange firewall solutions like Microsoft ISA or hardware firewalls. Next on the scale are large Cisco PIX or Checkpoint firewalls used for large businesses or Internet Service Providers.
