Default IP address is set to 172.16.1.209, but the detected external address is actually 109.70.25.64. This is typically the result of being behind a NAT firewall, and should be corrected on the module configuration page.

In System Settings -> Virtualmin Config -> Network Settings, you would want to change “Default IP address for DNS records” to “Automatically detect external address”.

That will make sure that the DNS entries added to your system use your external address, and not your internal address.
