On this page, Open Door Networks is attempting to build as complete a list as possible of port numbers commonly used on the Macintosh. We would like this page to become a resource for DoorStop X Firewall and Who's There? users and for the Macintosh community in general. Please contact us with additions, corrections, and other comments on this page. Thank you.

Please also check "Internet Security for Your Macintosh and iPhone: A Guide for the Rest of Us" for more details on port usage.
