Hi everyone, We're dealing with an internal DNS server that needs to be used externally. It's not working properly and we're struggling to resolve any issues. The server is running Windows 2019, and we've also turned on DNS through the firewall.

Refers to the intended application outside of internal testing or demonstration.

Find the internal IPs from the external ones.

We are relying on NOIP for our DNS services, though the fees are becoming high. We aim to manage our own DNS servers, especially for reverse lookups.

Consider alternatives such as L2TP/IPSec VPN on Windows Server 2019 or a proxy server for web services. An Apache proxy could work for simpler setups. It might be feasible, but it would be quite challenging and could compromise security.

Do you possess a website address? You can't proceed without it.

You wouldn't need a VPN unless you're managing our own systems. These tools are used internally, not for external users. No one outside is accessing anything.

Sure, we definitely have a domain name.

You're correct, if you designate your primary DNS server as the one from him, the client will rely on that server for all queries. This can create delays if the server is external. It's generally not considered a good approach.
