Murus Lite is the entry level member of the Murus family. It's a simple front end for the OS X PF network firewall and features inbound filtering, bandwidth throttling, logging, presets and ports management. Interface is based on icons, leds, and collection views. Set the firewall rules by dragging and dropping icons and selecting checkboxes. No need to type code or to understand PF syntax. An expanded PF configuration view shows the PF ruleset with a clear representation of rules with icons, symbols, and dynamically generated comments for each rule. Murus Lite is free for both personal and commercial use.
