Redistribute User-ID Information From an On-Premises Firewall to Prisma Access

In cases where users are at a branch location or HQ that is secured by an on-premises next-generation firewall with user-based policies, and they need to access resources at another branch location that you have secured with Prisma Access, you must redistribute IP address-to-user name mappings from the on-premises firewall to Prisma Access.

The following figure shows an HQ/Data center with an on-premises next-generation firewall with existing IP address-to-username mapping. Prisma Access connects to the firewall with either a service connection (SC-CAN) or remote network connection (RN-SPN), and the on-premises firewall redistributes the mapping to Prisma Access.

The following figure shows a Prisma Access service connection or remote network connection being used to redistribute the mapping. You can use any route path over an IPSec trusted tunnel for privately addressed destinations to redistribute this mapping.

To redistribute User-ID mappings from an on-premises firewall to Prisma Access, complete the following steps.

Configure the on-premises firewall to redistribute User-ID information to Prisma Access.
From the on-premises firewall, select
Device
Data Redistribution
Collector Settings
.
Click the gear icon to edit the settings.
Provide a
Collector Name
and a
Collector Pre-Shared Key
to identify the on-premises firewall as a User-ID agent.
Click
OK
to save your changes.
Configure Prisma Access to collect the User-ID mapping from the on-premises firewall.
From the Panorama that manages Prisma Access, select
Device
Data Redistribution
Agents
.
Make sure that you have selected the
Service_Conn_Template
(for service connections) or the
Remote_Network_Template
(for remote network connections) in the
Templates
drop-down at the top of the page.
Add
a User-ID Agent and give it a
Name
.
Select
Host and Port
.
Enter the IP address of the MGT interface or service route that the firewall uses to send user mappings in the
Host
field.
For the MGT interface, you can enter a hostname instead of the IP address.
Enter the
Collector Name
and
Collector Pre-Shared Key
, using the values for the collector you used for the on-premises firewall in Step 1.
Select
IP User Mappings
.
Click
OK
.
