About:
Murus Firewall is a native macOS GUI for managing the built-in pf firewall. It simplifies the creation of rules for filtering network traffic, port forwarding, and NAT. The tool provides a visual interface to configure complex packet filter settings without editing pf.conf files manually.
Key Features:
  • Visual rule configuration for macOS pf firewall
  • Support for NAT and port forwarding
  • Traffic monitoring and logging
  • Pre-configured rule templates
Use Cases:
  • Configuring a secure firewall on macOS without command-line
  • Setting up port forwarding and network address translation
  • Monitoring real-time network traffic and blocked connections
Alternatives:
  • Little Snitch – Focuses on outgoing network traffic monitoring and control, whereas Murus manages the native pf firewall for incoming and routing rules.
  • LuLu – Open-source outgoing firewall, similar to Little Snitch, while Murus provides a GUI for the system's underlying packet filter.
