GlobalProtect in Proxy Mode

Configure the GlobalProtect app to forward traffic to
Prisma Access
using explicit proxy, without creating a VPN or IPSec tunnels.
Where Can I Use This?
What Do I Need?
  • Prisma Access (Panorama Managed)
  • Prisma Access (Cloud Management)
If you'd like to use this feature in your
Prisma Access
environment, get in touch with your account team to learn more.
  • Prisma Access

  • GlobalProtect app version 6.2 for Windows or macOS
  • Content release version 8700-7994
  • Prisma Access

With
Proxy
mode, the GlobalProtect app provides always-on internet security. In this mode, the GlobalProtect app proxies traffic to
Prisma Access
based on forwarding rules and logic from the PAC file, hosted in
Prisma Access
or in your environment. This is useful if you have an existing (legacy) proxy architecture or have a requirement to maintain your proxy architecture for regulatory or compliance reasons.
The agent-based proxy feature facilitates coexistence and interoperability of the GlobalProtect app with third-party VPNs wherein you can secure your mobile users’ internet traffic through the GlobalProtect app to the explicit proxy and use the third-party VPN of your choice to secure private application access.
When running the GlobalProtect app in Proxy mode, Autonomous DEM (ADEM) and host information profile (HIP) functionality is not supported.
In this scenario, the GlobalProtect app sends internet traffic to
Prisma Access
based on the PAC file rules you define, while the endpoint routes access to your private applications through a third-party VPN using an IPSec/TLS tunnel.

Configure GlobalProtect in Proxy mode.
  1. Enable the agent-based proxy functionality for mobile users on Prisma Access.
    1. Enable explicit proxy.
      1. Select
        Settings
        Prisma Access
        Setup
        Mobile Users
        and click
        Explicit Proxy Setup
        .
        If you're using Strata Cloud Manager, go to
        Workflows
        Prisma Access
        Setup
        Mobile Users
        and click
        Explicit Proxy Setup
        .
      2. In the Infrastructure Settings area, click

        Explicit Proxy URL
        .
    2. Enable Agent Proxy
      and click
      Save
      .
    3. Choose the
      Prisma Access
      where you want to support mobile users.
      For the best user experience, if you're limiting the number of locations, choose locations that are closest to your end users. If a location isn't available in the country where your mobile users reside, choose a location that is closest to the mobile users.
    4. Configure a proxy auto-configuration (PAC) file for explicit proxy that meets the following requirements.
      • For your PAC file to work with the GlobalProtect app-based proxy, it cannot exceed 1 MB.
      • The Proxy statement in the PAC file must use the
        Prisma Access
        FQDN you configured above.
      • The PAC file must be configured to bypass 3rd party VPN traffic.
      Sample PAC file:
      function FindProxyForURL (url, host) { /* Bypass localhost and Private IPs * / var resolved_ ip = dnsResolve (host) ; if (isplainHostName (host) || shExpMatch (host,"* ‚local") || isInNet (resolved_ip,"10.0.0.0", "255.0.0.0") || isInNet (resolved ip,"172.16.0.0","255.240.0.0") || isInNet (resolved_ip,"192.168.0.0","255.255.0.0") || isInNet (resolved ip, "127.0.0.0", "255.255.255.0" )) return "DIRECT"; /* Bypass Non-HTTP * / if (url.substring (0,4) == "ftp: ") return "DIRECT”; /* Bypass VPN */ if (shExpMatch (host, "vpn. acme.com") || shExpMatch (host, "gateway. acme.com" )) return "DIRECT"; /* Bypass Private Apps */ if (shExpMatch (host,"internalapps. acme.com" ) ) return "DIRECT"; /* Forward to
      Prisma Access
      */ return "PROXY acme-demo.proxy.prismaaccess.com: 8080";}
    5. Select
      Settings
      Prisma Access
      Setup
      Explicit Proxy

      Advanced Security Settings
      Authentication Settings
      .
      All requests to the proxy are authenticated. However, if you're passing IDP flows through the proxy, then you need to bypass them for the authentication to be successful.
      In this example, we're bypassing the GlobalProtect portal and Okta, but please customize these to the IDPs that you use.
  2. Set up the GlobalProtect Portal, authentication, and configure Proxy mode for the GlobalProtect app.
    1. Enable GlobalProtect for mobile users and set up the GlobalProtect portal.
    2. Enable GlobalProtect proxy mode for
      Prisma Access
      in the GlobalProtect app settings to send internet traffic to the agent-based proxy.
      The GlobalProtect connect method doesn't apply in proxy mode as it is always on.

Panorama

Configure the GlobalProtect app in Proxy mode.
If you convert a single-tenant
Prisma Access (Panorama Managed)
deployment to multitenancy, only the first tenant (the tenant you migrated) supports this feature. Also, in this first tenant, you must set up your policy rules in the predefined Explicit_Proxy_Device_Group rather than in a custom device group. Any subsequent tenants you create for the multitenant deployment after the first do not support this feature.
  1. Enable the agent-based proxy functionality for mobile users.
    1. Enable explicit proxy.
      1. Select
        Panorama
        Cloud Services

        .
      2. Configure
        the explicit proxy setup to specify an
        Explicit Proxy URL
        .
    2. Select
      Use GlobalProtect app to Authenticate
      to enable the agent-based proxy functionality.
    3. Enter the
      PAC (Proxy Auto-Configuration) File
      URL. Ensure that you enter a port of 8080 in the PAC file.
      • Ensure that you enter a port of 8080 in the PAC file.
      • For your PAC file to work with the GlobalProtect app-based proxy, it cannot exceed 1 MB.
      • The Proxy statement in the PAC file must use the
        Prisma Access
        FQDN you configured above.
      • The PAC file must be configured to bypass 3rd party VPN traffic.
      Sample PAC file:
      function FindProxyForURL (url, host) { /* Bypass localhost and Private IPs * / var resolved_ ip = dnsResolve (host) ; if (isplainHostName (host) || shExpMatch (host,"* ‚local") || isInNet (resolved_ip,"10.0.0.0", "255.0.0.0") || isInNet (resolved ip,"172.16.0.0","255.240.0.0") || isInNet (resolved_ip,"192.168.0.0","255.255.0.0") || isInNet (resolved ip, "127.0.0.0", "255.255.255.0" )) return "DIRECT"; /* Bypass Non-HTTP * / if (url.substring (0,4) == "ftp: ") return "DIRECT”; /* Bypass VPN */ if (shExpMatch (host, "vpn. acme.com") || shExpMatch (host, "gateway. acme.com" )) return "DIRECT"; /* Bypass Private Apps */ if (shExpMatch (host,"internalapps. acme.com" ) ) return "DIRECT"; /* Forward to
      Prisma Access
      */ return "PROXY acme-demo.proxy.prismaaccess.com: 8080";}
    4. Select the
      Connection Name
      for the explicit proxy setup that you configured.
    5. Select the
      Locations
      and the regions where you want to deploy your explicit proxy for mobile users.
      Prisma Access
      adds a proxy node into each location that you select. Explicit proxy supports a subset of all
      Prisma Access
      . For the best user experience, if you are limiting the number of locations, choose locations that are closest to your end users. If a location is not available in the country where your mobile users reside, choose a location that is closest to the mobile users.
  2. Bypass identity providers (IDPs).
    All requests to the proxy are authenticated. However, if you're passing IDP flows through the proxy, then you need to bypass them for the authentication to be successful.
    In this example, we're bypassing the GlobalProtect portal and Okta, but please customize these to the IDPs that you use.

    4. Commit and push to the
      Explicit_Proxy_Device_Group
      .
  3. Configure the GlobalProtect portal.
    In Proxy mode, the connect method you set does not change the behavior of the proxy functionality. Even if you set an on-demand connect method, all internet-bound traffic will still be proxied for always-on internet security.
    1. In the Onboarding section, click
      Configure
      .
    2. On the
      General
      tab, specify the
      Portal Name Type

      Use Default Domain—
      If you select this option, your portal hostname uses the default domain name: .gpcloudservice.com. In this case, simply enter a Portal hostname to append to the default domain name.
      Prisma Access
      will automatically create the necessary certificates and publish the hostname to public DNS servers.
      Use Company Domain—
      Select this option if you want the domain in the portal hostname to match your company domain name (for example, myportal.mydomain.com).
    3. Select an
      Authentication Profile
