I edited the PowerDNS conf file, and added another IP address in the allow-axfr-ips=
section, but that IP address is still not allowed to do anything. I checked the firewall, that is also not interfering.
So, my question is do I need to reload, and or restart the pdns_server
binary?
Yes, you need to reload the service if you change configuration. Most if not all services do not actively monitor changes to configuration files to see if they have changed.
