General informations

Help text

This option adds a new iptables `hashlimit' match.

As opposed to `limit', this match dynamically creates a hash table of limit buckets, based on your selection of source/destination ip addresses and/or ports.

It enables you to express policies like `10kpps for any given destination IP' or `500pps from any given source IP' with a single IPtables rule.
