2TB TC Version 7.5 DNS Proxy to Local Server - How?

Question

Ok, so TC Proxies DNS. Great. That means that DHCP clients get the TC IP (10.0.1.1) in my case as their DNS server. Here's the problem, I don't want TC to proxy to the ISP DNS, nor to OpenDNS,
nor to Google DNS, but to 10.0.1.2 which is my brand new mac MINI server providing DNS services.
The trouble is it will not allow you to set a local service as the primary DNS IP, only as the Secondary IP.
The problem is that aside from leaking internal network lookups to your upstream DNS service, it doesn't fail over to the secondary, so is essentially useless.
Apple, we need a way to point TC to an internal network DNS server.

Answer 1

Ok, Definitely this is a bug.
I decided to look into it again last night, and here's the findings.
First off, I decided to switch from google DNS to OpenDNS and so went
and change the DNS entries from 8.8.8.8 to the appropriate OpenDNS IP's.
Saved, rebooted, and the TC still had 8.8.8.8 as the DNS entry.... ***?
So, reset to factory settings.
Config everything again, and this time set the DNS to the internal 10.0.1.2/3
IP's. Voila, works great, kept the internal DNS and proxies to it just fine.
Enabled guest network, which hands out the TC as the DNS server, rather than
the servers on the internal network.
You should not have to reset to factory settings to reset the DNS entries.
Also, it would be better/desirable if the GUI allowed setting the DNS servers
for the primary and guest network individually. That way you can set the guest
to use something other than your ISP (eg. openDNS) and set the primary to use
the internal DNS server on say a mac-mini.
BTW, the reason that you want to do this is, is that you can then setup an internal
network (eg. home.net) and put devices on it, named in the local DNS server.
Anyway, it now works, but Apple pls fix, and document better.
