Configure Traffic Steering in

Prisma Access

Onboard your service connections, mobile users and remote networks, as applicable to your deployment.
Select
Panorama
Cloud Services
Configuration
Traffic Steering
.
(
Optional, mobile user deployments only
) Allow
Prisma Access
to accept and install the default route advertised over one or more service connections from the CPE by clicking the gear icon to open the Settings and selecting
Accept Default Route over Service Connections
.
Default routes have guidelines that you must follow when using them; for example, default routes are supported for mobile user deployments only and have no effect on remote network deployments. Be sure to review these guidelines before implementing default routes with traffic steering.

(
Optional
) Create a target group and assign a service connection to it.
In the

Target Service Connections for Traffic Steering

area,

Add

a group and give it a

Group Name

.

Add

a

Target

for the traffic, specifying the

Service Connection

to use with the target; then, click

OK

.

Palo Alto Networks does not recommend using multiple service connections (whether dedicated or non-dedicated) in a target service connection group that is referenced in a traffic steering rule. In addition, a given service connection can only exist in one target and you cannot add a single service connection to two different targets.

Choose whether to make the service connections associated with this target a dedicated service connection.

You can use a dedicated service connection to steer traffic to a third-party security stack or cloud that is not on your premises and does not need to participate in routing. To set a service connection to be used as a dedicated service connection, select
Dedicated for Traffic Steering Only
.
Dedicated service connections change their zones.
Deselect
Dedicated for Traffic Steering Only
if you will send both normal service connection-related and traffic steering traffic through the service connection; with this choice, the zone for the service connection remains as Trust.

Choose whether to enable or disable source NAT.

To disable source NAT for Dedicated service connections, select

Disable Source NAT for Dedicated SC

. Source NAT is enabled by default (the check box is deselected).

If you disable source NAT,

Prisma Access

uses your organization’s source IP addresses for the dedicated service connection. If you enable source NAT,

Prisma Access

uses the

EBGP Router

address of the service connection (

Panorama

Status

) as the source IP address, even after the traffic egresses from the dedicated service connection.


Create rules for the target you created and apply them to the target.
In the
Traffic Steering Rules
area,
Add
a traffic steering rule.
in the
General
tab,
Name
the traffic steering rule.
In the
Source
tab, specify rules for source traffic.
In the
Source Address
field, specify one or more of the following objects, or select
Any
to have traffic from any source go to this target:
An IP address
An address object that you created in Panorama (
Objects
Addresses
)
A Dynamic Address Group (DAG)
An External Dynamic List (EDL) using IP addresses or URLs
In the
Source User
field, specify rules for source user traffic. You can specify the following user information:
Users
Enter users in either the
domain
/
user
or the
user
@
domain
format.
User groups
Use full distinguished names (DNs) when entering user groups.
Users configured on Panorama (
Device
Local User Database
Users
)
User groups configured on Panorama (
Device
Local User Database
User Groups
)
If you use address objects, DAGs, EDLs, users, or user groups, specify them as
Shared
to share them with all device groups in
Prisma Access
. In addition, do not enter 0.0.0.0/0 in address objects, DAGs, or EDLs; instead, enter 0.0.0.0/0 directly in the rule.
Prisma Access automatically populates users from the mobile users device group only.
In the
Destination
tab, specify the following values:
In the
Destination
area, specify one of the following criteria, or select
Any
to have traffic processed by the rules in the
URL Category
field:
An IP address or prefix
An address object that you created in Panorama (
Objects
Addresses
)
A Dynamic Address Group (DAG)
An IP address-based External Dynamic List (EDL)
Do not enter 0.0.0.0/0 in address objects, DAGs, or EDLs; instead, enter 0.0.0.0/0 directly in the rule.
Leave
Any
selected to pass all traffic to be processed by the rules in the
URL Category
area. If you specify rules in the
Destination
, and
URL Category
areas,
Prisma Access
processes the rules in the
Destination
category first.
In the
URL Category
field, enter a custom URL category (
Objects
Custom Objects
URL Category
) When you create a custom URL category, enter URLs in all lower case. Traffic steering supports custom URL and predefined URL categories.
You can use wildcards with the URLs in URL categories. The following wildcard formats are supported:
*.example.com
*.fqdn.example.com
The following formats are not supported:
*
*.*
*example.com
example.com/ (trailing slashes in URLs are not supported in URL categories that are used with Traffic Steering)
example.com/
path
(only domain names are supported)
*fqdn.example.com
fqdn.example.*
URLs in custom URL categories use the same URL pattern matching as that used by next-generation firewalls.
Use the following guidelines when configuring destination options:
If you specify a URL category,
Prisma Access
only matches HTTP and HTTPS traffic, even when service is set to Any.
Do not create a custom URL category with a type of
Category Match
.
Do not create a custom URL category with the name
Custom_URL_Category_TFR
because, for deployments that are migrated from
Prisma Access
1.7 to 2.0, URLs entered in the URL area from 1.7 are moved to a custom URL category named
Custom_URL_Category_TFR
number
, where
number
is a number appended to the custom URL category.

In the
Service
tab, specify a service type.
Specify
service-http
to forward HTTP traffic and specify
service-https
to specify HTTPS traffic. Select
Any
to forward traffic of any service type.
In the
Action
tab, select the
Target Group Name
that you want to apply to the traffic steering rule.
Forward traffic to the specified service connection target, or send the traffic directly to the internet without going through the service connection.
To have
Prisma Access
forward traffic to a service connection target, select
Forward to the target
; then select the
Target Group Name
.
To have
Prisma Access
forward traffic directly to the internet without first sending it to a service connection, select
Forward to the internet
.
