Question : Routing DNS from external to internal addresses

Hi Guys,

We've got 4 VM servers which are named vm1.domain.local vm2.domain.local etc and we can access them through web browser to the relevant address.
We have access to our external DNS records so how would i go about setting this up externally and internally so that we can access these VM's for an external source (i.e we can type in https://vm1.domain.com
I've added the vm1, vm2 etc to the external dns and pointed them to our external IP but as we have 6 servers i'm not sure where this would go.
Hope this makes sense and hope you can help
Thanks
