Connect to the Unifi Controller via a browser. Under Settings -> Networks, select the WAN network. Set:

  • IPV4 Connection Type: PPPoE
  • Username and password: As supplied by A&A
  • IPV6 Connection Type: Using DHCPv6
  • Prefix Delegation Size: As shown on the A&A Configuration Page (usually 64)


Select Save and then navigate to the Devices section of the Unifi Controller. When the Security Gateway status changes from Provisioning to Connected, then Restart the Security Gateway by selecting Restart at the right of the screen. You must restart your Security Gateway for changes to take effect.

show ipv6 route
show interfaces

  • IPv6 Interface Type: Prefix Delegation
  • IPv6 Prefix Delegation Interface: WAN
  • IPv6 Prefix ID: Leave blank
  • All other settings as default
