- Connection tracking keeps a record of what packets have passed
- through your machine, in order to figure out how they are related
- into connections.
-
- This is required to do Masquerading or other kinds of Network
- Address Translation (except for Fast NAT). It can also be used to
- enhance packet filtering (see `Connection state match support'
- below).

- help
- 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.
