Microsoft recently introduced custom Entra Private Access traffic forwarding profiles in public preview. Administrators can now provide different sets of private applications to selected users, groups, devices, and device platforms. This post explains how the profiles are assigned and prioritized, how to configure one, and how the new local network option handles overlapping address space.

Forwarding Profiles v1

Previously, organizations could assign the default Private Access traffic forwarding profile to selected users and groups, but they could not create separate Private Access profiles with different acquisition rules for different target groups. That made it difficult to give Windows devices one set of private application destinations and mobile devices another. Administrators could still control access through application assignments and Conditional Access, but the traffic the client acquired was less tailored to the user or device.

Forwarding Profiles v2

Global Secure Access (GSA) provides default traffic forwarding profiles for Microsoft traffic, Private Access, and Internet Access. Administrators can also create custom Private Access profiles and scope them to users, groups, devices, and device platforms. During the preview, a tenant can have up to 10 custom Private Access profiles.

Policy Processing

GSA evaluates traffic against the Microsoft, Private Access, and Internet Access profile types in that order. Traffic that matches none of them is not forwarded to the service. This order is separate from the priority used to choose between multiple applicable Private Access profiles.

Multiple Profiles

Each custom Private Access profile has its own acquisition rules, assignments, status, and priority. Assign a priority from 101 through 199. A lower number represents a higher priority. When more than one enabled Private Access profile applies to the same user and device, the client uses only the highest-priority applicable profile. The application rules from the other profiles are not combined with it.

Configure a Custom Private Access Profile

In the Microsoft Entra admin center, go to Global Secure Access > Connect > Traffic forwarding. Select Create new traffic forwarding profile, then Private access profile. Enter a descriptive name and, optionally, a description. Set a priority from 101 through 199 and choose whether the profile is enabled. Select Next, review the settings, and select Create. Note that the new profile has no acquisition rules or assignments until you configure them.

Acquisition Rules

Open the new profile and select Acquisition rules. Choose whether to include Quick Access destinations, then select the Private Access applications whose destinations the profile should acquire. Adding an application to a forwarding profile determines which traffic the client captures. Users must also be authorized to connect to the application’s resources.

Including Quick Access Destinations

Including Quick Access adds its configured destinations to the acquisition rules of this profile alongside the selected Private Access applications. This can provide a common set of destinations across custom profiles, but it does not change the Quick Access application’s configuration or grant users access to its resources. Confirm that the intended users are assigned to Quick Access as well as to the forwarding profile.

Assignments

Under Assignments, select View next to User and device assignments. Choose All users and devices or Selected users and devices, then save your selection.

Next, select View next to Device platform assignments and choose the supported platforms that should receive the profile. A device must match both assignment conditions. For example, selecting a user group and Windows limits the profile to Windows devices used by members of that group.

The new profile appears in the traffic forwarding list by priority, as shown here.

On an assigned client, open Advanced diagnostics > Forwarding profile to confirm that the expected Private Access application segments are present, as shown here.

Prefer Local Network

The Windows GSA client includes a Prefer local network option for cases where a local subnet overlaps with a configured private application destination. When an administrator enables the option, it appears in the client settings. A user can select it to keep applicable local subnet traffic on the local network, such as traffic to a printer or screen casting device, instead of having the client acquire that destination for Private Access. Microsoft introduced the option in Windows GSA client version 2.32.294.

The Problem It Solves

Overlapping private address space can make a local destination look like a destination defined in a Private Access application segment. For example, a user’s home printer and a corporate resource might both use 192.168.1.50. Prefer local network lets the user favor the directly connected local destination in this situation, such as when printing or screen casting.

Intelligent Local Access

Intelligent Local Access (ILA) serves a different purpose. It uses configured DNS probes to identify a corporate private network and can then send traffic directly to specified Private Access applications available on that network. Prefer local network addresses when there is an overlap between the device’s local subnet and a Private Access destination, such as a printer on a home network. ILA depends on a matching configured private network and application. An address overlap alone does not trigger it.

Summary

Custom Private Access traffic forwarding profiles give administrators more control over which private application destinations the Global Secure Access (GSA) client acquires for different users and devices. Assignments determine who receives a profile, while priority determines which profile applies when assignments overlap. The Prefer local network option also helps Windows users reach local devices when their subnet overlaps a Private Access destination.
