+ # Event filtering: This clause allows you to filter certain traffic,

+ # filter-sets in positive or negative logic depending on your needs.

+ # By default, the daemon receives state updates following an
+ # event-driven model. You can modify this behaviour by switching to
+ # polling mode with the PollSecs clause. This clause tells conntrackd
+ # to dump the states in the kernel every N seconds. With regards to
+ # synchronization mode, the polling mode can only guarantee that
+ # long-lifetime states are recovered. The main advantage of this method
+ # is the reduction in the state replication at the cost of reducing the
+ # chances of recovering connections.
