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

    Configure EdgeOS DNS forwarding.

    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 the CLI or Config Tree.
    2. Set forwarding servers and disable using WAN DNS.
    3. Commit and save.

    EdgeOS CLI

    configure
set service dns forwarding name-server <FIREWALLDNS-PRIMARY>
set service dns forwarding name-server <FIREWALLDNS-SECONDARY>
set service dns forwarding system
delete service dns forwarding dhcp eth0
commit; save

    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.
