The configuration of BIND is stored under /etc/bind/, where the most important file is named.conf. This is the general configuration file. Zone database information is stored in db.domainname files under the same directory.

ZMC does not offer a dedicated component to edit BIND configuration, instead, the Text editor component offers preconfigured templates for this task.

If you go back to the DNS configuration component you can see the structure of the named.conf file with the values entered for query-source and forwarders.

In addition, this tool is suitable for editing the named.conf file only. If you want to host zone database files (db.domainname) on the firewall, you can edit the files separately if you create a new file in the Text Editor component. However, for forward-only nameserver configurations editing the named.conf file is generally sufficient.
