Enable the DHCPv6 Stateless Server

For clients that use StateLess Address Auto Configuration (SLAAC) in conjunction with the Prefix Delegation feature (Enable the IPv6 Prefix Delegation Client), you can configure the threat defense to provide information such as the DNS server or domain name when they send Information Request (IR) packets to the threat defense. The threat defense only accepts IR packets and does not assign addresses to the clients. You will configure the client to generate its own IPv6 address by enabling IPv6 autoconfiguration on the client. Enabling stateless autoconfiguration on a client configures IPv6 addresses based on prefixes received in Router Advertisement messages; in other words, based on the prefix that the threat defense received using Prefix Delegation.

This feature is only supported in routed mode. This feature is not supported in clustering or High Availability.

Before you begin

Add a DHCP IPv6 Pool object. See Create the DHCP IPv6 Pool. This object defines the server parameters included in the IR messages.

Procedure

Step 1	Select Devices > Device Management and click Edit () for your threat defense device. The Interfaces page is selected by default.
Step 2	Click Edit () for the interface you want to edit.
Step 3	Click the IPv6 page, and then click DHCP.
Step 4	Click DHCP Server Pool, and choose the object you created earlier. Enable the DHCPv6 Server
Step 5	Check Enable DHCP for non-address config to inform SLAAC clients about the DHCPv6 server. This flag informs IPv6 autoconfiguration clients that they should use DHCPv6 to obtain additional information from DHCPv6, such as the DNS server address.
Step 6	Click OK.
Step 7	Click Save. You can now go to Deploy > Deployment and deploy the policy to assigned devices. The changes are not active until you deploy them.
