CONFIG_NF_CONNTRACK:
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. It can also be used to enhance packet
filtering (see `Connection state match support' below).
