I have Cable Internet from Comcast (Xfinity) with a 256Mbps connection.
Then I have a WRT1900AC Router (with the wireless turned off). The configuration is as follows:
- Subnet: 10.10.1.0/24
- Router: 10.10.1.1
- Primary DNS Server: 10.10.1.2 (This is my DC)
I have a home lab, it consists of about 45 servers, and about 5 workstations.
I have an AD Server with DNS setup in my home network.
All of the servers and computers are connected to that DC.
Everything works fine, however on occasion I get DNS errors. I am sure it is because of my DC is a bit of an older machine (its physical), so it may have a hard time of keeping up with the translations.
What I would like to do is to somehow have the DNS all point to the internet providers Default DNS Server, unless it is looking for mydomain.local, or any internal DNS (machine names, a records, mx records, etc...) that I specify.
What should I do? Is it possible to set that up to have the default DNS Server point to that of my internet provider, but still specify somehow specify what the internal DNS is before it reaches out to the outside DNS servers?
UPDATE: What if in my router I have the DNS Servers as follows: DNS 1 - 18.104.22.168 (ISP First DNS) DNS 2 - 22.214.171.124 (ISP Second DNS) DNS 3 - 10.10.1.2 (Internal AD DNS Server)
