hope that help for you.

See if you can turn on masking if your domain registrar / dns host offers that… Masking won’t cover internal links by itself but will help with what you want.

Also, you might touch base with EasyWP to see if they can help you by mapping in your domain to their service and setting ‘A’ records with the host IP.

You’ll probably want a Cname for your ‘www’ machine name also.
