the issue

I imported a cpanel account which had subdomains. These subdomains DNS were populated with my server's internal IP address (10.0.0.47) and not my public one (123.123.123.123).

IPs changed for privacy/security.

The parent account's DNS was correctly set.

the 2 subdomains are

• demo.example.com
• search.example.com

additional

I was under the assumption when you imported a cpanel account with subdomains a special subdomain would be created (i.e. not sub server).

• Virtualmin --> system settings --> configuration category: Advanced --> Allow creation of sub-domains`

My current setting

Thanks

Was the issue here that the parent domain had the public IP, but the sub-domain imported from the same cPanel backup was given the internal IP?

Yes this is correct.

Ok I see the cause of this now - we'll fix it in the next release.
