Internal and External subdomains

[foureight84]

I have a public domain, ex example.com set to forward to blog.example.com on Cloudflare. I also use example.com locally for other subdomains, ex, ns1.example.com.

I have a Conditional Forwarder Zone for example.com with "This Server" checked for forwarder option. All local subdomains entries added, ex ns1.example.com pointing to 10.0.0.4. However, when I try to access just example.com or blog.example.com, it doesn't resolve. I thought internal resolver would be used if there are no entries. I am definitely missing something. I have looked for solutions and a lot of posts say use Conditional Forwarder Zone but specific details weren't very clear.

You'd need to define a FWD record that points to a public resolver, in order to catch those domains and send them to the internet

Awesome! Thank you! How about the base domain itself? example.com

SFLR. From my tests if you configure the FWD record on the base domain then the forwarding is used for both example.com and *.example.com by default. Only when you define records for specific subdomains will it behave differently

Thanks for the post. A conditional forwarder zone with FWD record that uses "This Server" will resolve the domain name normally as if it the forwarder zone did not exists. So it should work but it still depends on how the zone is configured. I would suggest that you share a screenshot of the forwarder zone here or send it to [email protected] so that the issue can be understood better.
