Notify message from slaves

[Fuat Demir (Garanti Teknoloji)]

Hi all,

I have 2 slave 1 master server.
master is located in different subnet from the slaves.
Lets say, 10.1.1.1 (ns1) and 10.1.1.2 (ns2) are the real ip addresses of the slaves which have public NAT address for allowing queries from internet for authoritive zones. These public address lets say 1.1.1.1 (ns1) and 1.1.1.2 (ns2).
In conf file of slaves i have a statement that "notify no".
When i configured conf file and reconfigure in slaves, i see transfer logs like this,

in the xfer log of ns1, it says "notify: info: client 1.1.1.2#25998: received notify for zone 'xxx.com'

in the xfer log of ns2, it says "notify: info: client 1.1.1.1#25998: received notify for zone 'xxx.com'

Please note that, ns1 recieves notify form the public address of ns2 and ns2 recieves notify from the public address of ns1.
In both slave server, domain names for ns1 and ns2 are the public addresses of itselves.

And as a result, because i do not wait any notify from the public address of ns1 and ns2 (also private address, only waiting notify from the master one), in foo these notifications are refused for both.

In my opinion it works like this:
for xxx.com domain, ns1 and ns2 are the NS (lets say ns1.xxx.com and ns2.xxx.com)
when i reconfig on slaves, it resolves the public address for xxx.com domain and sends notifiaction to this public adddress (1.1.1.1 and 1.1.1.2).
However, it should not send any notification beacuse of notify statement.

slaves and master DNS are BIND 9.6.1-P3.

Does anyone have any idea about this problem ?

Regards,
Fuat
