The secondaries know  the address of   the primary and  contact it  every N
seconds (you fix the N seconds time  in the SOA RR) to  see if the serial #
(also set in the SOA  RR) has changed; if it  has, then they will  download
the entire zone again.

The GATEWAY kernel option is not  used anymore (more or  less, it just says
what is the default). Use the sysctl variable for that:

sysctl net.inet.ip.forwarding

to see the value and

sysctl -w net.inet.ip.forwarding=1

to set it.
