DNS setttings, basic documentation
Hey Team, I'm looking for the most basic instructions on how to configure DNS. For example looking to understand...
-what is primary and secondary DNS?
-why does the documentation say to set Firewalla Gold router as the DNS? How would I do that?
-why is the primary DNS settings in a VLAN set for and IP address on the VLAN and not the IP address of the Gold Router?
Thank you!

For each of your networks, the interface IP of the Firewalla Gold should also be your primary DNS server in the DHCP configurations. When a device connects to your network and requests and IP address (DHCP), the Firewalla will tell the device 'here is your IP, I am your gateway, and I am your name server'. There is no secondary in this instance because you only have one Firewall/Router, and if that device were down you wouldn't get anywhere anyhow.
In larger environments (or smaller environments that do not have an internal device which can handle DNS, like Firewalla is doing), your firewall is generally NOT providing name resolution services, and so you'll either define primary and secondary ip addresses to corporately managed name servers within the environment, or you might opt to use public name servers such as OpenDNS, Quad9, CloudFlare, or Symantec. If you wanted to live life on the edge and had no concern for privacy, you might use the name servers provided by your local ISP. But seriously, don't.

Don't know if this is of any help but maybe.
