Pfsense dns setup

Local dns with pfsense 2.4

The sheer number of menus in the web configurator can be overwhelming if you’re new to pfSense, and you may be wondering what some of them are for. That’s why we put together this summary of the pfSense web configurator menu. It lists all of the menus found in a standard pfSense installation and gives a quick overview of each with screenshots (IP and MAC addresses are blurred).
When a page is blank because nothing is configured, we show a screenshot of the service’s configuration options underneath it. Clicking the green Add button usually brings up the configuration choices.
Open a web browser on a device linked to your firewall and type https://[your LAN IP address] to access the pfSense webconfigurator. It’s 192.168.1.1 by chance. In the login tab, enter your username and password. The default values are admin and pfsense. You’ll be taken to the pfSense Dashboard once you’ve logged in, which shows valuable high-level information about your firewall.

I wrote this guide many years ago to expose my thought and setup to the scrutiny of networking experts and to include a clear but detailed guide for less experienced users. I’d like to express my gratitude to anyone who approached me with questions or provided input that helped shape this guide into what it is now. Please don’t hesitate to contact me by email if you find any bugs, configuration issues, or areas that need more explanation.
I revised my guide several times to make it a foundational piece in a series of guides aimed at helping users develop a SOHO framework capable of self-hosting multiple services and promoting migration away from cloud providers to take care of their own data.
While this baseline configuration is largely unchanged from the previous version, a few areas have been enhanced as a result of increased or refined expertise, or as a result of the pfSense 2.5.0 update, including:

Providing local dns with pfsense

A DNS server indexes the resources on your own network. The Domain Name System (DNS) helps classify all resources on the Internet. Any IT specialist, including DNS administrators and programmers, analysts, and CTOs, needs to know how to handle a DNS server. The theory and practice of administering DNS using dig and other DNS server technologies are covered in Managing DNS Critical Training. This course will have you saying “Eureka, I’ve got it!” in no time, thanks to its abundance of realistic examples and excellent visualizations to assist in comprehension.

Pfsense dns resolver setup

Instead of bringing in more DNS servers that would never be used for anything, maybe someone should fix/nuke the misleading notice from the GUI? (For more details, see https://github.com/freebsd/freebsd/blob/master/include/resolv.h#L128)
As a result, prior to his update, that type of configuration should have failed the input validation. Anything on a “truly locally connected” network or pointed to by a static route in the configuration is considered “local” by the code, and a DNS server on such a network/address does not have a gateway listed.
More validation checks are probably necessary, and if the current static route for that address already points to the selected gateway, then it’s fine. However, it is simple for the user to either delete the static route or not pick a DNS server gateway (and then it will use the static route they already set up).
