How to Change DNS on HPE Aruba (Instant On / Central)
By [FILL IN], [FILL IN] · Last updated
Aruba hands out DNS through the network/DHCP settings.
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
- Instant On: Network > select the network > Advanced > IP and DHCP; set DNS to custom with the FirewallDNS addresses.
- Aruba Central gateways: Configuration > Interfaces > DHCP Pools, set DNS servers.
- Aruba CX switches with DHCP: dhcp-server vrf default > pool LAN > dns-server <FIREWALLDNS-PRIMARY> <FIREWALLDNS-SECONDARY>.
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.
