[SOLVED]DNS best practice?

tbrandl

There are two ways to configure DNS:

One way:
- Allowing DNS outgoing for your internal nameservers
- internal nameservers forwarding to ISP-DNS
- ASG pointing to internal nameservers 

Another way:
- ASG forwarding to ISP-nameservers
- "request routing" on ASG for internal domain pointing to internal nameservers
- internal nameservers forwarding to ASG
 
Which way do you use? And why? Which is "officially preferred"?
Both configurations seem working good for me, we run the first alternative on our cluster, the second in branch offices without internal dns (domain dns reachable via site2site-vpn).

Thanks for your ideas!
Thomas

    Hi,
    The second is more secure, as it protects your internal nameservers from being 'poisoned'.

    Also, you don't have to do request routing, you can just have DHCP assign the internal nameservers' IPs.
