About MU-SPN behavior when IP Optimization function is enabled

y.saitou — Fri, 30 May 2025 04:38:58 GMT

For RN and SC, the IP address assigned from the service infrastructure IP is set as the loopback address, but
when IP Optimization is enabled, will the MU-SPN have an IP address assigned from the service infrastructure IP?
If so, is there a way to check that IP address using an API or something?

Hello @y.saitou , Yes, when IP Optimization is enabled in Prisma Access, the Mobile User Security Processing Node (MU-SPN) may receive an IP address assigned from the service infrastructure IP pool. This optimization helps reduce the number of IP addresses required for deployment while improving resiliency and simplifying allow-listing workflows. To check the assigned IP address using an API, you can retrieve Prisma Access IP addresses through the API. Specifically, you need to query the serviceType for gp_gateway and gp_portal to get the egress IP addresses used by Prisma Access. Also, querying the addrType for network_load_balancer will provide ingress IP addresses that may be relevant for your deployment. For more details on retrieving Prisma Access IP addresses via API, you can refer to the official documentation: https://docs.paloaltonetworks.com/prisma-access/administration/prisma-access-setup/retrieve-ip-addresses-for-prisma-access/ip-optimization?otp=concept-jpw_kc2_y2c.

I hope you find this helpful.
