already allow port 53(udp and tcp) for everyone .

4.now I have enabled querylog

5. Since i was thinking just wanna be easy so that I shutdown the slave
server , now I have already enable the slave server . but the serial number
is different with the master server ,even if I restart/reload the service
from slave server .

thank in advance for the help .
