[nsd-users] master to slave DNS notify and firewall

[Robert Blayzor]

Have one NSD master and multiple slave servers.

Notify from master to slave w/ AXFR works, however, it doesn’t appear that the master server is getting the “ACK” back from the slave that notify has been received.


Is there any info on the return traffic. I assume the master server is sending from unprived src port to dst port 53.

Is the ACK sent back from 53 to the master server?
