If any of the sites from the public DNS server are hosted locally you would
need those site on your internal DNS server, and they will need to resolve
to the IP of the server they are on.

e.g. the external DNS has a zone for domain.com, and all the records have
public IPs so people on the internet can access these sites.
How ever if any of the domain.com sites locally behind your router, you
would have to use the private IP from behind your router. The way I would
handle the situation is that say you only host www.domain.com locally and
all the others are hosted elsewhere, on your internal DNS create a zone
named www.domain.com and create a new host leaving the name field blank, and
give it the local IP of your webserver hosting the site. (click OK to create
the record anyway when it barks at you saying it now a vlid host name)
Doing it this way you only have to create the local records all the others
are forwarded to your external DNS to be given Public IPs.
