Firewalk X

If you're in need of a versatile configuration and maintenance utility for the Mac OS X built-in firewall, then Firewalk X is the software for you. What sets Firewalk X apart is its independence - it doesn't rely on the Mac OS X firewall, ipfw. Instead, it offers a range of features that make it an attractive option:

- TCP, UDP, and ICMP packet filtering - for both incoming and outgoing traffic.
- Self-optimization that aligns with current network activity.
- Interactive, real-time alerting.
- Time-expiring firewall rules.
- Compatibility with Mac OS X's built-in firewall.
- Ability to restrict network access to specific applications.
- User and IP address-specific application rules.
- Detailed logging of events.
- Automatic setting changes according to network locations.
- Multithreaded for optimal performance.
- Port scan and packet flood detection.
- Nicely integrated with Mac OS X for seamless operation.
- Full Unicode support.
- Localized in English, French, and German.

The latest release of Firewalk X comes with some great improvements:

- The issue of connections being broken when switching between active/inactive modes is now fixed.
- Improved network interface detection. Even interfaces like tunnels can now be detected.
- Displayed application names are now localized as expected.
- Some settings now stick and work correctly, such as the status item and alert users.

We recommend that you give Firewalk X a try. It's a powerful tool for keeping your Mac OS X firewall optimized, configurable, and secure.
