PFconf offers a set of scripts to simplify using basic packet filters, enabling easier network security management.
With PFconf, you only need a single rule no matter how many mail servers and protocols you have. The script automatically takes care of necessary permutations, so you don't have to worry about forgetting any rules. These scripts are designed to be fairly simple, with plenty of space for comments explaining rule orders and preferences.
Additionally, PFconf is small, efficient, portable, and easy to use. Plus, with the promise of NAT handling and management scripts coming soon, you'll have even more features at your disposal. Target conversion for Cisco ACLs and OpenBSD's PF will probably follow shortly after. Overall, if you're looking to simplify your packet filter management, PFconf is worth checking out.
