Fwctl is a program that intends to make it easier to configure a tight firewall. It provides a configuration syntax that is easier to use and more expressive than the low-level primitives offered by ipchains. It supports multiple interfaces, masquerading and packet accounting. Fwctl doesn’t replace a good security engineer, but it can make the job of the security engineer simpler.
