How to Change DNS on ASUS (RT / ZenWiFi)
By [FILL IN], [FILL IN] · Last updated
ASUSWRT supports WAN DNS and DNS Director.
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
- Open router.asus.com > Advanced Settings > WAN.
- Set "Connect to DNS Server automatically" to No and enter <FIREWALLDNS-PRIMARY> and <FIREWALLDNS-SECONDARY>.
- LAN > DHCP Server: optionally set the DNS server there too.
- LAN > DNS Director (newer firmware): set Global redirection to Router to prevent bypass.
- Apply.
Verify it works
- Renew DHCP on a client (Windows:
ipconfig /renew, macOS: reconnect Wi-Fi). - Run
nslookup example.comand check which server answered. - Open the live log in your dashboard. New lookups should appear within seconds.
