    Configure Multiple Portals in Prisma Access

    Learn how to configure multiple portals with multiple authentication methods.
    You can configure two portals based on port numbers in the same Prisma Access tenant, with each portal supporting a different authentication method. Enable this feature to migrate mobile users from one authentication method to another without creating a new Prisma Access tenant. This configuration enables greater authentication flexibility by allowing you to gradually move users to cloud-based authentication, without the need for a separate Prisma Access instance.
    Prisma Access with GlobalProtect multiple portals uses a different port number for each portal within the same tenant. Configure the first GlobalProtect portal using the standard port 443. When you enable the multiple portal feature, Prisma Access configures a second GlobalProtect portal using an alternative port 8443, and allows connections to the second portal using the same FQDN as the first. The multiple portals feature supports only two portals per FQDN.
    When a user connects to the portal using port 443, the traffic is sent to the first authentication portal with no change to the IP address. This flow is unchanged from configurations without the GlobalProtect multiple portals feature. When a user connects using port 8443, the traffic instead hits a destination NAT rule. This leads the user to the second authentication portal at a different IP address. After authenticating at either portal, the user is forwarded to the gateway with the authentication override cookie. This feature depends on the authentication override cookie settings, and these settings are enabled for both portals and on gateways.
    The following table describes GlobalProtect multiple portals support with combinations of authentication methods and certificates using legacy authentication (such as RADIUS or LDAP) on the primary portal and cloud authentication (such as SAML or SAML with CAS) on the secondary portal.
    Primary Portal User AuthenticationSecondary Portal User AuthenticationConnection Method Options
    Legacy, No certificateCloud, No certificateUser logon (always-on, on-demand)
    Legacy, <auth profile selection> AND Client Certificate
    Note: Certificate profile must be the same.

    Legacy, <auth profile selection> OR Client Certificate
    Multiple portal configurations don't support clients using only client certificate for authentication
    		Cloud, No certificate
    User logon (always-on, on-demand)
    Pre-logon (always-on, on-demand), if certificate
    Legacy, <auth profile selection> OR Client Certificate
    Multiple portal configurations don't support clients using only client certificate for authentication
    Cloud, <auth profile selection> OR Client Certificate
    Multiple portal configurations don't support clients using only client certificate for authentication
    User logon (always-on, on-demand)
    Pre-logon (always-on, on-demand), if certificate
    Ensure the following before you configure multiple portals:
    • Both portals have the same certificate profiles or no certificate profiles
    • Allowlist associated with the authentication profiles should be the same
    • When you accept a cookie for authentication override on the portal, ensure the cookie lifetime is the same on the portal as well as on the gateway
    • Multiple portal configurations don't support using only client certificate-based authentication
    When configuring multiple GlobalProtect portals with Traffic Steering, don't configure Accept Default Routes over Service Connections (PanoramaCloud ServicesConfigurationTraffic SteeringSettingsAccept Default Route over Service Connection); if you do, mobile users can't connect to the secondary portal.
    1. Contact your Palo Alto Networks account team to activate this functionality.
    2. Configure a mobile user and the authentication method for it.
      The minimum required version of the GlobalProtect Client version is 6.1.
    3. Select Cloud ServicesConfigurationMobile Users—GlobalProtectSettingsAdvanced.
    4. Enable Multiple Portal for Multiple Authentication Methods.
      The new portal appears for the 8443 port for the same tenant. This portal inherits the configuration settings from the original port, which is port 443.
    5. Edit the portal configurations to update the authentication settings.
      1. Click the portal hyperlink or select PanoramaTemplatesNetworkGlobalProtectPortals and click the portal hyperlink.
      2. In the Authentication section, Add a Client Authentication with a different Authentication Profile.
      You can edit only the Client Authentication and Certificate Profile authentication settings.
      If you use certificate-based authentication in both portals, ensure that the gateway does not have certificate-based authentication.
      This feature enables the authentication override settings to generate cookies for both portals in the GlobalProtect app settings.
      This feature enables the authentication override settings to generate and accept cookie for both portals in the tunnel settings.
    6. Commit all your changes to Panorama and push the configuration changes to Prisma Access.
      1. Click CommitCommit and Push.
      2. Edit Selections and, in the Prisma Access tab, make sure that Mobile Users is selected in the Push Scope, then click OK.
      3. Click Commit and Push.
    7. Add the portals manually or using endpoint management software in the GlobalProtect app.
    8. Verify if you can connect to both portals with different authentication profiles for the gateway.
      1. Log in to your Windows machine.
      2. Connect to the portals in your GlobalProtect app.
        When you change the connection between portals of different authentication methods, authenticate the user login.
        If the authentication cookie expires when you connect to the 8443 portal and switch to the manual gateway, GlobalProtect connects to the Best Available Gateway.
        If your GlobalProtect app uses cached portal configurations, fall back to portal does not work.
      3. View logs for both portals in MonitorLogsGlobalProtect to see the portal and authentication information.
    If you're using SAML-based authentication for the secondary portal, enter the values as follows while integrating:
    • Single sign on URL: Enter https://Portal-FQDN:443/SAML20/SP/ACS
      Portal-FQDN is the FQDN for the Prisma Access portal
      Use portal 443 even if you have configured the secondary portal (8443).
    • Audience URI (SP Entity ID): Enter https://Portal-FQDN:443/SAML20/SP
