Select all relevant LAN interfaces that will receive
and forward the requests and
The DNS service configuration is now enabled on the ION
device and will answer DNS queries on the selected interfaces. After testing
that the Prisma SD-WAN DNS service is configured per requirements,
the DNS server IP addresses can be changed in the DHCP scope to
the respective default gateway (ION LAN interfaces), the branch
subnets, or specified manually on systems with static IP configuration.
With the Prisma SD-WAN system deployed and the DNS service
enabled, the branch systems utilizing SaaS services no longer rely
on the centralized data center resources to function. In the event
of a data center failure, none of the SaaS application services
will be affected. This is due to all necessary functions delivered
by the ION device through the DNS service and the ability to put
trusted SaaS application traffic directly onto the internet with
a scalable and straightforward path policy rule.
