Current Version: 2.0.3 'L' Pro (November 12, 2007)

sunShield is a preference pane that manages the built-in firewall in Mac OS X (which makes it similar to Flying Butttress / BrickHouse, except that Flying Butttress is a standalone application).

Core features include:

  • PPC and Intel ready
  • Supports IPFW2, shipped with Tiger.
  • Use advanced actions, and advanced protocol options.
  • Easily turn firewall ON / OFF
  • Create all kind of basic or dynamic rules.
  • Lets you also create rule manually, from sunShield's interface.
  • Review dynamic rules, time left and parent rule.
  • Enforce rules based on user sending packet.
  • Enable or disable logging, system wise.
  • Live logs, in sunShield, lets you use ToolRules (sniffing, debugging...)
  • Export rule base to an rc.firewall script, handy to deploy IPFW configuration on BSD compatible systems.
  • Re-order rules with simple drag and drop.
  • Edit rules with a double click on them, right click them to edit as new rule
  • Automatically save and restore rules across reboots.

Apart from being released natively for Intel- and PowerPC-based Macs, version 2.0 Pro adds/changes the following:

  • Edit (and replace) or Edit as a new rule.
  • Import and export a whole ruleset from one file, in one click.
  • Enhanced template support.
  • New interface, bringing better feel when using the pane.
  • New key protocol in order to support demo version. (2.0.2)
  • Two glitches fixed in French interface. (2.0.2)
  • Added: Refresh button on Logging window. (2.0.3)
  • Fixed: Edit as new rule broken. (2.0.3)
  • Fixed: Debug output logged on dynamic rules, even when debug output disabled. (2.0.3)
  • Fixed: A bug introduced with Leopard's build 9a581. The bug is not in Leopard, but in the way sunShield Pro tries to read some system data. (2.0.3 'L')

These are applications that are newer and of potential interest, but which I haven't yet selected for permanent inclusion. Have a look, and let me know if you think they deserve to be part of the permanent collection!
