Hi folks,

After configure the iptables for masquerade the zone transfer traffic. I've found new issue, below the log on slave :

zone domain.com/IN/external-view: serial number (2015022302) received from master 10.xx.xx.xx#53 < ours (2015022303)

The zone on the slave doesn't update.

The reason the zone does not update is given in the message. The serial number on the slave copy of the zone file is greater than the serial number on the master's copy. You need to figure out why that is so and fix that issue. Then the slave should update.
