When you nslookup an external DNS server do you get the external IP?
When you nslookup your internal DNS server do you get the internal IP?

If yes to both, then you have the correct records and IPs and it should work
on both sides of your firewall.
Note- No access should be given to the external DNS by internal clients
accept as forwarded by your internal DNS server.
No external users should have access to your internal DNS.
