subdomain

I know this is probably quite easy to do, but I might just have the right search sorted out... so here is the situation:

We have example.com set up as a hosted server along with app1.example.com, app2.example.com and a few others. What I would like to do is set up the right zone file to also make our internal server addressable from the outside world as internalapp.example.com.

This server sits behind a firewall (pfsense) and is hooked up to the world via a cable modem that is technically on DHCP from our ISP, but has had the same external IP for the past 15 months so far.

What would be the best way to set this up?
