DNS using OPNSense

In this video, I'll continue building my "Heavy Metal Cloud" by setting up the first server: OPNsense. While OPNsense is traditionally used as a firewall, I’m taking a different approach by configuring it specifically for DNS management within a private cloud environment. I’ll walk through the entire process from hardware selection and installation to advanced configurations like Unbound DNS, setting up DHCP pools, and creating custom DNS overrides for private domains (like .lan). What you’ll learn: - How to install OPNsense - Setting up Unbound DNS and external resolvers - Creating DNS Overrides for custom local domains. - Testing your setup with nslookup. *To follow along, check out my GitHub page!
