DoorStop X 1.0 Enhances Mac OS X's Firewall -- Back in 1998, Open Door Networks shipped DoorStop, the first firewall for the Mac. The program was subsequently licensed to Symantec for Norton Personal Firewall, and now Open Door has released DoorStop X, a new version for Mac OS X 10.3 Panther and 10.4 Tiger. Although Mac OS X has had a built-in firewall since Mac OS X 10.2 Jaguar, and the version in Tiger finally offers rudimentary logging of denied access attempts, DoorStop X provides far better logging (particularly in concert with Open Door's Who's There? Firewall Advisor utility) of both allowed and denied access attempts. DoorStop also features a more graphical interface that makes it easier to understand your configuration at a glance, and most important, the program enables you to open up a particular port to a specific IP address or range of IP addresses, thus eliminating the all-or-nothing approach of Mac OS X's built-in firewall. Through 15-Aug-05, DoorStop X costs $40, or $60 when bundled with Who's There. Educational discounts are available for multiple license packs. A fully functional trial version (2.2. MB download) works for 30 days; Who's There has a fully functional, 10-day trial version (also 2.2. MB). [ACE]
