BPetronio,

 

 

If you've configured external DNS queries to be delegated to the listener IP, it needs to be the public/routable address.

 

 

This will be your traffic flow:

 

 

1. User queries your DNS record

 

2. DNS record hits LC

 

3. LC responds to query with an available IP

 

4. User sends request to that IP

 

 

Since the user must send its traffic to your public/routable address, you must return a public address.

 

 

I'm confused about your DMZ private DNS servers...What are those used for?
