The ConnTrack plugin tracks the number of entries in Linux's connection tracking table.
In order to do stateful packet inspection (SPI), the Linux packet filter IP-Tables keeps track of established connections in the connection tracking table. This allows packets belonging to an established connection to be accepted quickly and only new connections will go through the entire firewalling logic.
