I am hoping I have this right. So when I setup my zones in DNS, use the public IP address for DNS (so example it would say ns1.domain.com routable IP)
There is one problem with using ISP config for name resolution for the interanal network, I don't know how to setup a zone for the internal network. I use my firewall's DNS for internal name resolution with DNS forwarding to level 3 for items outside of the network. Also, since my DNS server share the same public address, should I only port forward to the primary DNS server? I see even though I don't have rules for the secondary it still get queried and send out responses.
By the way, thank you for helping me with this, I really do appreciate it
