Plan and set up your Prisma Access service infrastructure.
To set up your cloud service infrastructure for remote
sites 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 the
network backbone that connects your remote sites, mobile users,
headquarters and 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, 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.
