DNS between DMZ and local network
hi all,
I have a AD integrated DNS for my private network (192.168.x.x). Additionally I have a web server on my DMZ with ip 10.x.x.x. I have setup a staic host "A" record on my DNS pointing to the web server. So, I have no problem accessing the web server by it's name from my 192.168.x.x network.
However, from my web server I am not able to access any computer by its name that's on the 192.168.x.x network.
Having said that, on my web server the IP is configured as 10.x.x.x (with appropriate subnet and gateway). The primary DNS server is my ISP's address and there is no secondary defined. Of course, I tried pointing the secondary DNS server address to my DNS server on 192.168.x.x and it did not help me to access any computers by its name.
Can someone please help me on how I can go about to accomplish the above task?
FYI: I am able to ping between two network without any problems. The routing is all setup and working fine.

I have tried pointing to the internal DNS as I mentioned before. On the web server, The preferred is currently set to ISP's DNS and for the alternate I tried putting in 192.168.x.x (the internal DNS server IP).
However, it did not solve my problem. Are you saying that I should set the preferred DNS to my local DNS and use ISP's DNS as the alternate?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You'd have to point it at the internal DNS server (as Preferred).
Then to resolve by name along you would need to add either a Primary DNS Suffix or a DNS Suffix Search List to the web server. Otherwise, you're limited to getting names in the form host.domain.com.
