Hi Brian, Thanks for the quick response.
Let me try to explain why I am running this setup to give some information and possibly find a better alternative way. We have several resolvers/recursors installed for clients/systems use and they're working as intended. The authoritative server has a private zone. Authoritative server should respond/answer for queries to this private domain if they originated from a select list of IP addresses. And authoritative server should respond/answer for queries for all other domains normally. The reason for forwarding all requests to the Authoritative server is due to the fact that this combo server should not be a public resolver/recursor. Hope this gives more information to understand the setup. Thanks again for your help.

Say for example via Lua script with setAA() function perhaps? No - I'm afraid you can't do it this way. Your authoritative server must be bound to port 53 if it's accepting queries from the outside world. You options are: 1. Run your recursor and authoritative server bound to two different IP addresses (or in separate VMs or containers with their own IPs) or 2. Don't list your authoritative server in the NS records, and instead use it as a "hidden primary". That is, you have two or more additional nameservers on public IPs, which are listed in NS records, and they get their zone content from the hidden primary (either by a zone transfer from x.x.x.x:5300, or by database replication) Final note: please don't use forward-zones to forward all queries to an authoritative server, since it's not authoritative for the whole Internet. You should rarely need forward-zones at all: as long as the NS records for your domain point to your authoritative servers, the recursor will find them by itself. Forward-zones are normally used for private domains which can't be delegated (e.g. localhost, 168.192.in-addr.arpa) HTH, Brian. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
