![]() Previously, the only way around a cellular carrier’s hard-coded DNS settings was to use a VPN to tunnel your traffic - a massive hassle. You’re no longer stuck using whatever DNS server your cellular carrier maintains. With iOS 14 (and macOS Big Sur) now natively supporting DoH, you can now force your device to use a custom DNS server - even while you’re using cellular data. I was trying to use it as Client > Unbound > AdGuard Home > External DNS (Cloudflare, Quad9, NextDNS etc.)Ĭredits: AdGuard Home setup guide you still problems you should visit serverbuilds discord! Link: serverbuilds.DNS over HTTPS (DoH) is a relatively new protocol for performing DNS queries over the HTTPS protocol. I found this setup works perfectly with HAProxy (Split DNS (DNS Overrides) Tutorial 2022/08: HAProxy + Let's Encrypt Wildcard Certificates + 100% A+ Rating) and other weird setups like “ Bypassing a CGNAT with Wireguard” ( GitHub - mochman/Bypass_CGNAT: Wireguard setup to bypass CGNAT with a VPS) If you have multiple VLANs or LANs then duplicate the rule and change it to the relevant Interface and address. If you want to force you OPNsense clients to use AdGuard you need to do following:Īdd a new Firewall rule to forward all DNS (Port 53) traffic to AdGuard:įirewall → NAT → Port Forward Interface: LANĭestination port range: From: DNS - To: DNS If you want to check on what IP’s AdGuard listens you can go to # guide (“ Setup Guide” on top of AdGuard WebUI). Click Test (it should show you green notification “ Specified DNS servers are working correctly”, then click Apply. You should see green “Play” indicator on top of this page after refresh.ģ.1 Now you need to configure AdGuard, navigate to opnsense_ip:3000ģ.2 I set Admin interface to my main LAN (192.168.1.1) as the only listen interface and via port 81 (OPNsense uses port 80 and 443 so select something other than this for AdGuard listen port and if you configure AdGuard’s SSL settings)ģ.3 DNS Server listen interface select ‘ All’ on Port 53.ģ.4 Now go to Settings> DNS and set “ Upstream DNS servers”, “ Bootstrap DNS servers” and “ Private reverse DNS servers” to “ 0.0.0.0:53350”. Now you can login back to OPNsense and continue.ģ.0 Go to: Services: Adguardhome: General and tick “ Enable”, then click Save. More public DNS providers you can find here: Known DNS Providers | AdGuard DNS Knowledge BaseĢ.6 If you use “ Dnsmasq” you need to change port to other than 53 (In my setup it’s “ 5335”)Ģ.7 Reboot your OPNsense so it will bind Dnsmasq and Unbound to different ports (not necessary, but i had bug where 53 was still “already in use”).

Hi! Some people ask on Discord if they can run OPNsense with AdGuard Home, so my answer is YES!
