DNS Forwarder Domain Override for Zone Transfers?
-
I have a Windows Server 2016 VM on Azure that I want to use my on-prem pfSense DNS server for giving out private IP addresses accessible over a VPN tunnel. But sometimes the tunnel goes down unexpectedly and then the Azure DNS server responds with the public IP addresses. This messes up my mail delivery, and potentially other tasks. So I want to set up a DNS server on the VM, and transfer the zone information from my on-prem pfSense. However, the VM DNS server will not transfer because pfSense is not the SOA for example.com. I am wondering if Domain Override will allow pfSense to actually do the transfer? And if I give as the source the VM's IP, will it only affect the VM? I don't want all of example.com's subdomains to only come from pfSense for the on-prem network.
