2. On the selected template page, click Deploy.
   
3. On the Deploy Template page, specify values for the following:
   1. Instance details:

      17. Specify values for other parameters as required, and click Review + create.
4. On the Review + create page, review the details and click Create.

After the instance is deployed with the template, the WAF starts up with IPv6 enabled. The instance is deployed with the IPv6 internal and IPv6 external IP addresses attached to it. This is a dual-stack deployment. All access to the Barracuda WAF instance is on the IPv4 IP address, and clustering is also performed on the IPv4 IP address. However, you can create services using the IPv6 IP address that is configured as the System IP.
