Internal DNS Setup

[ciscoboy]

Hi Team,

Need help for setting up internal dns. I use other DNS servers on my internal network , Windows AD 2008 but it's not working.

Please see diagram for details..

any other alternative with this config:

on client workstation:

primary: 172.25.85.20 (internal dns)
secondary: 172.25.85.91 (pfsense)

You have to give your AD/DC some external DNS server/s itself. In AD DNS, propertied of the DNS server, Forwarders tab, you can put the IP address of your pfSense (and let the pfSense DNS Forwarder then resolve external names) or put IP address(es) of your favourite DNS server/s on the internet.
Edit: and this looks like a duplicate of your other thread - don't post twice please!
