I opened all highport, but still the zone cannot transfer. I used Bind9 and my named.conf is very standard, and I put the allow-transfer on global options. Do you have other suggestion? Yes, put the allow-transfer statement into the zone definitions. That's how we configured our named and how it works for us.
