Plan and set up your Prisma Access service infrastructure.
To set up your service infrastructure in the cloud for
your remote network locations and mobile users, you must provide
a subnet that does not overlap with other IP addresses that you
use internally. Prisma Access uses the IP addresses within this
subnet to establish a network infrastructure between your remote
network locations and mobile users, and from your service connections
to your headquarters and/or data center (if applicable). This infrastructure
enables Prisma Access to determine the service routes for services
such as DNS, as well as enable other inter-service communication.
Because a large number of IP addresses are required to set up the
infrastructure, you must use a /24 subnet (for example, 172.16.55.0/24).
This subnetwork is an extension of your existing network, and therefore,
cannot overlap with any IP subnets that you use within your corporate
network or with the IP address pools that you assign to your Prisma
Access for users deployment.
