A large retailer has deployed all of its stores with the same IP address subnet.

When the "Overlapping Subnets" checkbox is selected during the Remote Network onboarding process in Prisma Access, the deployment enables Private Application access using Prisma Access for Users(ZTNA or Private Access). This feature is designed to handle scenarios where multiple sites use the same IP subnet by leveraging NAT (Network Address Translation) and segmentation to avoid conflicts.

Since overlapping subnets can create routing challenges for direct remote network-to-remote network communication, Prisma Access does not support Remote Network-to-Remote Network or Mobile User communication in this case. Private application access is supported as Prisma Access correctly routes requests based on application-layer intelligence rather than IP-based routing.
