When the clients are connected remotely, they will need to have your
internal DNS number, in order to resolve internal names. So, this would
have to appear in the client setup. If the client is resolving DNS with the
ISP-provided DNS, it will not work for your internal machines.

How you implement this varies with the software package, but that's the
source of your issue. It's not on the concentrator, it's on the client.
(or whatever configuration the concentrator pushes to the client if that's
how your system works).
