Howdy -- I would recommend configuring your router to give your server a static IP. Otherwise, whenever your server renews it's DHCP lease, it could end up with a different IP address, which might confuse things a bit.

With the setup you're describing though -- what I would recommend is to go into System Settings -> Virtualmin Config -> Network Settings, and there, make sure that "Default IP address for DNS records" is set to "Automatically detect external address".

Then, whenever a new domain is created on your server, it will use the proper IP address for the DNS records.

After doing that, then verify that if you go into System Settings -> Re-Check Config, that not errors are detected there.
