brendan wroteif i am reading this correctly, you have one DNS server configured for use by the clients, and do not want to configure a second DNS server for you clients to use. that being said, you want the resolution/recursion that the second DNS server performs available to your clients.
if the above is correct, you would need to add the second DNS server to the "forwarders" list/directive in the first DNS server. see the BIND docs, chapter 6 and look for the section on forwarding.
I have one DNS Server to resolve my VPN Infrastructure. In that VPN, there is a Webserver too.
Client
|
Local DNS -> other Server ....
|
Local Router
|
INTERNET (VPN Tunnle)
|
VPNetwork
|
->DNS Server (this is the Server i wanted to add as a second DNS)
->Webserver
Now, if the client get´s only the DNS Server form the VPN Network, he cant resolve local Server and Internet Adresses.
To fix the Problem with Internet, i can push a second public DNS Server if the Firewall allow it. But whats about the local Server in the client LAN????
I would like to make a connection from anywhere via the VPN with my infrastructure. Whether I'm in the internet café or at a company. Whether I use my laptop or a foreign computer. In this case, I can not edit the local DNS. If I set another (second public DNS) DNS via DHCP push, I can´t (where the client is located) resolve the local server infrastructure anymore.
So I just want add my DNS server (VPN) to the local, existing DNS server.
Is that possible?
