IceFloor is the first and most advanced PF firewall frontend for OS X. IceFloor is now group based, like the old ServerAdmin firewall tool. Control filtering, bandwidth, logs, connections and custom PF configurations.

• create custom PF presets including custom rules, options, filtering and bandwidth rules
• mix IceFloor PF rules with your custom PF rules, interact with external applications like sshguard
• share Internet connection using PF NAT, assign per-client filtering and bandwidth rules and redirections
• browse PF ruleset with the new PF Rules Browser, display filtering, bandwidth and NAT PF rules and pipes
• analyze PF logs with numerical and graphical statistics
