Our contractor setup two DNS servers each with internal and external

Please can I get information on how to do it if possible and what
commands to use.
The comprehensive documentation is a good place to start:
https://docs.powerdns.com/
Your question isn't clear though, and I don't think you've really
thought it through.
1. Are you talking about PowerDNS Recursor
<https://docs.powerdns.com/recursor/settings.html> or PowerDNS
Authoritative <https://docs.powerdns.com/authoritative/settings.html>?
Which version?
2. On the one hand you say that the DNS servers have both an internal
and external IP, which suggests there are two interfaces. But then you
talk about a firewall, and the subject line says "NAT".
For binding interfaces, see options "local-address" (for listening for
queries) and "query-local-address" (for packets sent outbound to other
nameservers).
However, it sounds to me like this is actually a networking problem,
i.e. how to configure NAT on your firewall to forward traffic to and/or
from PowerDNS. If so, I don't think it's relevant to the PowerDNS
community. You would be better off talking to your local network
administrator instead.
