PetacommPetacommPetaGuard gives you a clean, unified interface for managing iptables, nftables and ufw — with rule history, rollback, dry-run mode and instant alerts when rules change. Stop memorizing iptables syntax.
Linux has three major firewall backends — iptables, nftables and ufw — each with its own syntax, quirks and learning curve. PetaGuard sits on top of all three and gives you a single, consistent interface regardless of which distro or backend you are on.
Every rule change is written to a version-controlled log. You can diff any two snapshots, roll back to any previous state and preview what a rule change would do before applying it.
