    IP Address Pools for a GlobalProtect Mobile Users Deployment

    Learn how to allocate IP address pools in the
    Prisma Access
     Mobile Users—GlobalProtect deployment.

    Make sure that you have specified an IP address pool that allows enough coverage for the mobile users in your organization. It is important to remember that each unique user can use multiple devices to connect to
    Prisma Access
     at the same time, and each connected device requires a unique IP address from the pool. The addresses in this pool must not overlap with other address pools you use internally or with the IP subnet you assign when you Enable the Service Infrastructure.
    We recommend that the number of IP addresses in the pool is 2 times the number of mobile user devices that will connect to Prisma Access. If your organization has a bring your own device (BYOD) policy, or if a single user has multiple user accounts, make sure that you take those extra devices and accounts into consideration when you allocate your IP pools. If your pool space is limited, you can specify a smaller address pool; however, if your IP address pool reaches its limit, additional mobile user devices will not be able to connect.
    The UI validates that you enter valid IP subnets (for example, if you enter a pool with a subnet of less than /23, it will prompt you to change it). However, it does not check to ensure that you have allocated sufficient IP addresses for your deployment.
    This validation is not available if you configure locations using CLI. If you deploy all locations using CLI, we recommend that you add a /18 address in the Worldwide pool for mobile users.
    Prisma Access
     checks your configuration to make sure that you have specified the following minimum IP address pool:
    • A minimum of /23 (512 IP addresses) is required for either a Worldwide or regional address pool.
    • If an existing location is converted to a compute location, that location requires a minimum /23 subnet after the conversion.
    • If you do not onboard any
      Prisma Access
       gateways in a region, an IP address pool for that region is not required. For example, if you specify gateways in the US East, US Northwest, and US Northeast locations, you need to only specify an IP address pool for the North America & South America region. Conversely, if you enable mobile user locations in Europe without specifying either a Worldwide address pool or an IP address pool in Africa, Europe, & Middle East, your deployment will fail.
    • GlobalProtect mobile users consume the IP addresses in the location group first, then theater-specific IP addresses, then Worldwide IP addresses. For example, if you specify a pool for a location group and Worldwide, and you then exhaust the available IP addresses in the location group pool,
      Prisma Access
       then takes IP addresses from the
      Worldwide
       pool to use in that location group.
      If you specify more than one block of IP address pools,
      Prisma Access
       uses the pools in the order that you entered them during mobile user setup.
