KB : https://www.virtualmin.com/documentation/dns/slave-configuration In your KB article explaining the BIND master / slave setup there is an headline called.
Setting the Master IP Address
But I don't have the "module config" option described in the "BIND DNS server" module!? So how do I set the Master IP Address in the template for all new created DNS zones?
Secondly I also have some extra questions. - How do I deactivate the option "Add NS record for master server?" in the template for future DNS zone files going to be created? - Why does all the slave DNS serves getting listed as master DNS servers in the zone file on the slave servers?
I am normally using Windows DNS servers, so the BIND setup is not that straightforward for me regarding the above, sorry for that.
