"record-state" is similar to "keep-state", but it doesn't produce implicit O_PROBE_STATE opcode in a rule. "set-limit" is like "limit", but it has the same feature as "record-state", it is single opcode without implicit O_PROBE_STATE opcode. "defer-action" is targeted to be used with dynamic states. When rule with this opcode is matched, the rule's action will not be executed, instead dynamic state will be created. And when this state will be matched by "check-state", then rule action will be executed. This allows create a more complicated rulesets.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
