    How to Change DNS on Ubiquiti UniFi

    By [FILL IN], [FILL IN] · Last updated

    Change DNS per network or on the WAN in UniFi Network.

    Before you start

    You need a FirewallDNS account (see pricing). Sign in to your dashboard, register your public IP address and copy your DNS server addresses. Replace <FIREWALLDNS-PRIMARY> and <FIREWALLDNS-SECONDARY> below with them.

    Step by step

    1. Open UniFi Network > Settings > Networks and select your LAN.
    2. Under DHCP Service Management / DNS Server, untick Auto and enter <FIREWALLDNS-PRIMARY> and <FIREWALLDNS-SECONDARY>.
    3. Repeat for every network/VLAN.
    4. Settings > Internet > WAN: set DNS Server to manual with the same addresses.
    5. Optional: use Traffic Rules or Firewall to block DNS to other servers.

    Verify it works

    1. Renew DHCP on a client (Windows: ipconfig /renew, macOS: reconnect Wi-Fi).
    2. Run nslookup example.com and check which server answered.
    3. Open the live log in your dashboard. New lookups should appear within seconds.
