Configure a Split Tunnel Based on the Domain and Application

Configure a split tunnel based on the destination domain and application.
When you configure a split tunnel to include all traffic—IPv4 and IPv6—based the destination domain and port (optional) or application, all traffic going to that specific domain or application is sent through the VPN tunnel for inspection and policy enforcement. For example, you can allow all Salesforce traffic to go through the VPN tunnel using the
*Salesforce.com
destination domain. By including all Salesforce traffic in the VPN tunnel, you can provide secure access to the entire Salesforce domain and subdomains. You can configure a split tunnel without specifying a destination IP address subnet, which extends the split tunnel capability to domains and applications with dynamic public IP addresses, such as SaaS and public cloud applications.
When you configure a split tunnel to exclude traffic—IPv4 and IPv6—based on the destination domain and port (optional) or application, all traffic for that specific application or domain is sent directly to the physical adapter on the endpoint without inspection. For example, you can exclude all Skype traffic from the VPN tunnel using the
C:\Program Files (x86)\Skype\Phone\Skype
application process name.
Follow these recommendations when configuring a split tunnel based on the destination domain and application:
  • With a GlobalProtect license, you can enforce or apply split tunnel rules based on the destination domain and application to Windows and macOS endpoints.
  • ICMP requests such as for latency, jitter, trace route tests are not supported for split tunneling based on the destination domain.
  • Supported only on endpoints with Windows 7 Service Pack 2 and later releases and macOS 10.10 and later releases.
Use the following steps to configure a split tunnel to include or exclude traffic based on the destination domain or application process name.
  1. Before you begin:
    1. Select
      Network
      GlobalProtect
      Gateways
      <gateway-config>
      to modify an existing gateway or add a new one.
  2. Enable a split tunnel.
    1. In the
      GlobalProtect Gateway Configuration
      dialog, select
      Agent
      Tunnel Settings
      to enable
      Tunnel Mode
      .
    2. Configure the tunnel parameters for the GlobalProtect app.
  3. (
    Tunnel Mode only
    ) Configure split tunnel settings based on the destination domain. These settings are assigned to the virtual network adapter on the endpoint when the GlobalProtect app establishes a tunnel with the gateway.
    (
    Requires GlobalProtect™ app 5.2.
    )
    You can apply DNS traffic in addition to network traffic if you have already specified
    Both Network Traffic and DNS
    as the
    Split-Tunnel Option
    in the
    App Configurations
    area of your GlobalProtect portal.
    1. In the GlobalProtect Gateway Configuration dialog, select
      Agent
      Client Settings
      <client-setting-config>
      to select an existing client settings configuration or add a new one.
    2. (
      Optional
      )
      Add
      the SaaS or public cloud applications that you want to route to GlobalProtect through the VPN connection using the destination domain and port (
      Split Tunnel
      Domain and Application
      Include Domain
      ). You can add up to 200 entries to the list. For example, add
      *.gmail.com
      to allow all Gmail traffic to go through the VPN tunnel.
    3. (
      Optional
      )
      Add
      the SaaS or public cloud applications that you want to exclude from the VPN tunnel using the destination domain and port (
      Split Tunnel
      Domain and Application
      Exclude Domain
      ). You can add up to 200 entries to the list. For example, add
      *.target.com
      to exclude all Target traffic from the VPN tunnel.
    4. Click
      OK
      to save the split tunnel settings.
  4. (
    Tunnel Mode only
    ) Configure split tunnel settings based on the application.
    Safari traffic cannot be added to the application-based split tunnel rule on macOS endpoints.
    You can use environmental variables to configure a split tunnel based on the application on Windows and macOS endpoints.
    1. In the GlobalProtect Gateway Configuration dialog, select
      Agent
      Client Settings
      <client-setting-config>
      to select an existing client settings configuration or add a new one.
    2. (
      Optional
      )
      Add
      the SaaS or public cloud applications that you want to route to GlobalProtect through the VPN connection using the application process name (
      Split Tunnel
      Domain and Application
      Include Client Application Process Name
      . You can add up to 200 entries to the list. For example, add
      /Applications/RingCentral for Mac.app/Contents/MacOS/Softphone
      to allow all RingCentral-based traffic to go through the VPN tunnel on macOS endpoints.
    3. (
      Optional
      )
      Add
      the SaaS or public cloud applications that you want to exclude from the VPN tunnel using the application process name (
      Split Tunnel
      Domain and Application
      Exclude Client Application Process Name
      ). You can add up to 200 entries to the list. For example, add
      /Applications/Microsoft Lync.app/Contents/MacOS/Microsoft Lync
      to exclude all Microsoft Lync application traffic from the VPN tunnel.
    4. Click
      OK
      to save the split tunnel settings.
  5. Save the gateway configuration.
    1. Click
      OK
      to save the gateway configuration.
    2. Commit
      your changes.
