Public IP Address Scaling Examples for Mobile Users

Provides you with examples of how Prisma Access adds IP addresses for mobile user deployments.
The following examples illustrate the mobile user public IP address allocation process that Prisma Access uses during a scaling event or when you add a new location.
In the following example, you specified two locations in the Asia Pacific region for a new mobile user deployment: Sydney and Seoul. Each location is given two gateway IP addresses.
Then a large number of users log in to the Seoul location. To accommodate these extra users, Prisma Access adds a second gateway for the Seoul location, takes one of the gateway addresses from the first Seoul gateway (51.1.1.4) and assigns it to the second Seoul gateway. It then adds two additional IP addresses (51.1.1.5 and 51.1.1.6 in this example) and adds them to the two Seoul gateways.
Then you add another location, Tokyo, in the Asia Pacific region. Prisma Access creates two new IP addresses for the new gateway (51.1.1.7 and 51.1.1.8).
Each time you add a location or have a scaling event, you should retrieve the new egress and gateway IP addresses that Prisma Access assigned and add them to an allow list in your network. Prisma Access keeps two sets of IP addresses at all times for all active gateways in each location.
